Technically I think that would work: IF all of your wants are from the same team(s)! But I collect 3 sports and that would not work for me. If you eliminated everything from the wantlist, would the Chiefs or Royals ALONE push you past the 100K mark? If so, you'd mess yourself up pretty bad. If one team kept you under the 100K, adding the missing cards of the other team would still work in completion. But you'd still have to add all new cards one at a time.
What pushed me past the 100K was adding all missing STL Cardinals MLB cards. That was something like 114K at the time I did it. I already had thousands of cards listed for specific NASCAR drivers and MLB/NFL players. So the STL cards bumped me to around 150K. My wantlist is now about 210K and still not complete.
Nobody ever answered the question about having multiple collections and separate Wantlists in each one though. If that does work, it might be worth my time moving stuff to an extra collection (or 5 or so).
NO PWE's EVER!!! PLZ PM me 1st before sending any offer. ONLY selling cards as of March 2024. No trades or purchases right now.
