system prompts and model aliases

[aivanise]

It would be nice to have a possibility to add a system prompt (prompt prefix) to a model, or even better have aliases with a model and system prompt combinations, as most of us sysadmins wear many hats, i.e.

o3-mini-sysadmin = use an o3-mini agent with a system prompt "I'm a Linux systems administrator using bash, perl, python, docker, google cloud. Wrap any code you produce in markdown text blocks."

or

gpt-4.5-preview-manager = use gpt-4.5-preview with the system prompt "I'm a technical manager leading a small group of SREs in a mid sized company using GCP"

I hope you get the drift ;)
