Is there a way to share documents or image in your individual demiplane listing

I have been poking at the sort of game management profile I have for a test game. Just checking to see how well everything works. I noticed that you do have a journal but nothing to save text prop or an image to share with the players. Am I missing it?

I am liking how it all looks. Just checking to see what I can do with the tools.

You can share you screen once video is on as you probably saw but not sure about sharing documents/images.
