Is there a way to set a default prompt that works automatically with each new ChatGPT chat?

[dreinert1]

I'd like to set a default prompt that works behind the scenes rather than having to open a chat by using a command. Is this possible? Before lencx, I used MacGPT which had this feature, and it was simple and great. If there is no direct way, is there a work around?

Thanks in advance!

Best,
