Custom system prompts

[Stargate256]

Is your feature request related to a problem? Please describe.
I think that it would be good if it was possible to create custom system prompts, to have something like custom characters to chat with. I know it can be done with Modelfiles, but that doesn't work while using openAI compatable API.

Describe the solution you'd like
Adding a section to create custom system prompts and then select a system prompt when clicking "new chat".

Describe alternatives you've considered
The only alternative I can think of is copy-pasting the system prompt in when starting new chat.
