Request for Auto-Select Option in Content Sharing

It’s crazy how we don’t have an auto-select button for content sharing. Like, why can’t I just click one button so it only shares official 1st-party books with this group? Instead, I have to manually select the book I want to share, not just from the ones I own, but from every single book on the website. It’s tedious work that ends up giving my players access to content I don’t want them to have, just because I forgot to manually remove a book from sharing.

It's the old argument between convenience and control. Some people would prefer what you are asking for while others want finer control. Also, it would require Roll20 to maintain a list of what is or isn't 1st party content for every game system used on the site. Roll20 supports over 1,200 game systems.
