I have tried various ways to load my dupes and there seems to be no easy way. I have a lot of dupes from some sets, 3 or more of some cards, and up to 90% of the set. So, I've tried loading the complete set and subtract the cards I don't have, I've tried loading one card at a time, and I've used the "add from here to here" feature in some cases. I know the trick of "hitting the add button 2 or more times for larger quantities, which helps. One feature that would be helpfuI would be "remove from here to here". I spent close to 3 hours trying to load 1350 cards from 2010 Topps football, which has a lot of rookies in the set. Since I knew I had dupes of most of the set, I chose to use the "add from here to here" feature-3 times, for 3 sets,then add any over 3 or remove any less than 3. This works pretty well for most sets, but with all the rookies, there were 2, 3, even 4 variations for most of them. So, you have to remove all the variations, one by one, 6, 9, 12 cards. That's why I think the "remove from here" feature would help speed up the process. Even when you load complete sets to your collection, you have to remove all the variations. I'd love it if all the variations could be loaded at the end of the base set.
My question to the group, has anyone found an easier, quicker way to add larger quantities? Easier way to get rid of variations? Thanks.
