I don't think so. :(
I gave up on sorting through the library and downloaded lists of bundle games and I am in the process of building a database for them.
If you've mostly bought the big charity bundles, https://randombundlegame.com/ has them and has much better search/filter options than itch.io's native library.
(I have bought a swarm of TTRPG bundles that aren't in that set, hence the need for a database. Right now they're sprawled across half a dozen Google spreadsheets and a giant excel sheet with a list of 10k games.)
