[Feature] Change Systemprompt from a Modell in API

[Spittor]

Feature Request

Hi since the new version it look like i dont can change the systemprompt of a model by a api request, is it posibile or have i to change to an other application because without the abbilite to change the system-prompt from the api, i don't have longer a use case for gpt4all.

seems a bit like a crap update, sorry.
