[FEATURE REQUEST] Ability to cocreate the diagram with copilot.

[cpAtor]

Imagining an experience where I can chat to edit diagram or manually update the mermaid code as shown in the belowscreenshot.
This should also work if I open any saved markdown file and start chatting with @mermAId/iterate.

This will provide a true copilot experience and make it easy to iterate on the diagram. Currently It's very easy to create a diagram using mermAId but if I need to make a small change I have to type a lot more in chat than what I would do if I am editing the code. and making changes is iterative where I may need to make a small change once and a very big change after that. It will be great if I can make small change in code and big change using chat.
