5E Dungeon Master's Guide Rollable Tables

I recently bought the Dungeon Master's Guide on Roll20, primarily to save myself some work regarding treasure using the rollable tables. But, when I added the DMG into my campaign, the only tables I saw that were relevant to my needs were the magic item tables. Now, to be fair, that is very  useful and time saving, but there's no individual treasure, no treasure hoards, no art pieces, no gemstones- none of those show up as rollable tables. I did some research and I know why the first two aren't there (sucks, but I'll have to live with it), but I don't see why the art piece and gemstone tables aren't available as rollable tables. I can see them in the rules and I know I can recreate them as rollable tables myself, but doing so would be a timesink I'd rather spend on getting my campaign ready. Is there something I'm missing or am I really going to have to recreate the art piece and gemstone tables from scratch?

I understand the frustration as they are really great resources for games. And I know this isn't necessarily a practical solutions since it is basically "throw more money at the problem" but with a Pro subscription and API access you can automate the table creation from compendium items if that's something worth the extra subscription price to you.

I had a feeling as much. At this point, rather than spend the extra money, I think I'll just make a basic webpage that I can have open during game. I am a little disappointed since I do own a physical copy of the DMG, but bought this one thinking that the tables would be done for me so I wouldn't have to flip through the book. Thanks for the response, though. I appreciate it.

This thread just saved me $39.99. Thank you!
