Thanks! This was the answer I was looking for. I can find what I need without the handy addition of filtering by artist indexes. (Would still be really cool though).
I wonder how many of us are collecting these by artist instead of player? For example, I have the Ted Williams project 2020 card by Mr. Cartoon. I would much prefer the other 19 cards by that artist than the other 19 cards of that player.
For Project 70 I would like to get a many of the Lauren Taylor (artist) cards as possible, but I don't even know (or care) which players those will be.
Thanks for the answer!
