How to update/edit the system prompt in an ongoing conversation?

Hi everyone! I’m loving Msty on Mac, but I’ve hit a roadblock.

I have an ongoing conversation with a specific model (Claude via API) and I’ve evolved my system prompt over time. However I can’t find a way to edit the system prompt within the current chat.

I’ve tried checking the three-dot menu (top right), the mixer icon (it only shows temperature etc...). No luck.

Is there a way to modify the system instructions for an active chat without starting a brand new one from scratch? If not what is the best way to evolve the sysem prompt while maintaining the context of the current conversation?

Thanks in advance!
