[Feature]: Modify proxy settings based on request

[every-time]

🚀 Feature Request

I'd like to be able to set different proxy settings based on the requests that the browser makes when it visits a page.

Example

Let's say I have 2 proxies. I set proxy #1 for the browser context. I then visit a page, example.com. That page makes requests to load image and font resources. I'd like for those resources to load on proxy #2.

Motivation

Some tasks require the use of proxies. Certain proxies have bandwidth consumption limits. This can be mitigated by being able to change the proxy settings when loading certain resources.
