This is literally possible with a single click of a button or single click of 2 buttons depending what page you are on if you are using DriveThruComics, DriveThruFiction, DriveThru Cards, WargameVault, Dungeon Masters Guild (D&D), Pathfinder Infinite, Storytellers Vault, or DriveThruRPG. The only site where it makes sense not to give this option that Roll20 owns is Demiplane and that has more to do with how you get access to stuff on that site.
