enforce module boundaries templating

[KieranFleckney]

Before I ask for a feature request I wanted to ask here first to make sure I wasn't missing something. On this page Tag in Multiple Dimensions it has this layout (I have removed some for simplicity)

// project "client"
{
  // ... more project configuration here

  "tags": ["scope:client", "type:app"]
}

// project "admin"
{
  // ... more project configuration here

  "tags": ["scope:admin", "type:app"]
}


// project "client-feature-main"
{
  // ... more project configuration here

  "tags": ["scope:client", "type:feature"]
},

// project "admin-feature-permissions"
{
  // ... more project configuration here

  "tags": ["scope:admin", "type:feature"]
}

// project "utils"
{
  // ... more project configuration here

  "tags": ["scope:shared", "type:util"]
}

{
  // ... more ESLint config here

  // @nx/enforce-module-boundaries should already exist at the top-level of your config
  "@nx/enforce-module-boundaries": [
    "error",
    {
      "allow": [],
      // update depConstraints based on your tags
      "depConstraints": [
        {
          "sourceTag": "scope:shared",
          "onlyDependOnLibsWithTags": ["scope:shared"]
        },
        {
          "sourceTag": "scope:admin",
          "onlyDependOnLibsWithTags": ["scope:shared", "scope:admin"]
        },
        {
          "sourceTag": "scope:client",
          "onlyDependOnLibsWithTags": ["scope:shared", "scope:client"]
        },
        {
          "sourceTag": "type:app",
          "onlyDependOnLibsWithTags": ["type:feature", "type:ui", "type:util"]
        },
        {
          "sourceTag": "type:feature",
          "onlyDependOnLibsWithTags": ["type:ui", "type:util"]
        },
        {
          "sourceTag": "type:ui",
          "onlyDependOnLibsWithTags": ["type:ui", "type:util"]
        },
        {
          "sourceTag": "type:util",
          "onlyDependOnLibsWithTags": ["type:util"]
        }
      ]
    }
  ]

  // ... more ESLint config here
}

Okay so my quuestion is: Can i make one rule which allows a app to access a project with the same scope. To make it clear what I mean, currently every new app you add, you will need to add a new rule similar to theses one

        {
          "sourceTag": "scope:admin",
          "onlyDependOnLibsWithTags": ["scope:shared", "scope:admin"]
        },
        {
          "sourceTag": "scope:client",
          "onlyDependOnLibsWithTags": ["scope:shared", "scope:client"]
        },

Why i would want this is because every app in my repo has a feature library so i want to restrict every app to only their feature library. However, the only way you can do this is add another rule like above for each new app. Now if you have 50 apps that's rather annoying.

I was wondering if it was possible to do something like

        {
          "sourceTag": "type:app",
          "onlyDependOnLibsWithTags": ["scope:shared", "{{TAG}}"]
        },

This would replace {{TAG}} in the current list of tags against the project it is validating with the current tag it is checking agaist

Hopefully this makes sense to people.
