I added the insert set, and my son added the checklist.
As far as we could tell, there was no way to name them other than Checklist. Sometimes they say "Checklist 1-132" or something to that effect. Without seeing the other cards, it looks like other than them being 1 of 3, 2 of 3, & 3 of 3, there are no other "identifying marks". In this case, you can add "Checklist 1 - 185" in the Note2 field, and add the similar info for the other 2 cards.
We selected "No Team" for the 3 cards, and had "CL" in the Note field.
Enjoy adding the scans! :)
