If you mean you want to add all the base of Series 1, and none from series 2, that cant be done. What you could do is click the arrow beside the box for card #1, then Add From Here, then on the next screen, click #330 or whatever card ends Series 1. But I think that will pick up all the variations too. But maybe you want that.
I'm going to reevaluate how I collect after the new year. It's just getting way too expensive for the new stuff. Sometimes I just want to buy a pack, not a whole box or even blaster.
