Ability to exclude messages from export

I am a college student who uses AI a lot to make study guides/review exams. I usually like to export these to pdf and print them out. When printing out my review guide today, I saw that my prompt message was also included in the pdf.

It would be nice if there was a way to exclude messages so that I could have excluded my prompt message from being exported.

This is a very niche use case but I think it could be helpful for other users with different use cases as well 😅
