Extend Presets by Ability to stage part of conversation.

In prompt engineering area quite a lot of techniques like COT, few shots e.t.c. require to run a conversation from a specific point where some messages User/Assistant are already added into the chat in advance (staged).
It would be nice to extend the current presets with a such ability that would allow to use librechat in place of Open AI Playground as Prompt IDE.

Thanks I agree! Adding/removing messages at any point as well as conversation templates are planned!
