[Feature request] Use same taskdef for multiple deployments

[mhuebner]

Let's say we have 4 Services we want to deploy the same app (version) to.
The deployment is executed synchronously:

1. ecs-deploy deploys taskdef-2 which is based on taskdef-1 to service1
2. ecs-deploy deploys taskdef-2 to service2
3. ecs-deploy deploys taskdef-2 to service3
4. ecs-deploy deploys taskdef-2 to service4

How can one archive this?

A workaround would be to parse the command output of step 1 and to strip out the taskdef -> use this taskdef then in step 2,3,4.
Any chance to get this done with a combination of arguments in a current version?
