I am a couple cards short of collecting another set of a specific series. ie 1987 Topps Main Set. But I already have one set which I have put into my collection. I can't put the cards I am missing on my want list for that second, or third complete set because i already have it in my first complete set. So my question is this.... Can you create or develop a way to add complete sets to the collection, or like in my case, add a way to add cards to the want list that one might already have in completing another set of the same series.
