[Feature Request] Add ability to edit pre-prompt (and save them)

[Foul-Tarnished]

Would be great if wr could get a way to edit and save pre-prompt.

For inspiration, I like how Faraday app does it.
You can create agents, that have specific pre-prompts, model, model settings, etc.

Then you can create a conversation, or multiple ones, with them, like it instanciate them

Useful when you switch between pre-prompts, or just topics in general.

So I can have ine agent with a sprcific pre-prompt, saying he's an IT expert for example, and another saying he's a music theory expert, or whatever.

Useful when you want to delete your history and start a new conversation too, as we cannot delete messages or rollback as of right now
