### Before Requesting

- [X] I have searched the existing issues, and there is no existing issue for my feature request

### What feature do you want?

I would like the ability to perform multi file context-aware edits similar to Cursor and Copilot Edits (currently in Beta) https://code.visualstudio.com/docs/copilot/copilot-edits

For example, if I ask for an additional screen to be added to my existing application, then the system will not only add the screen, but also update the code where the screen needs to be created and presented.
