I was thinking about this also. As a player collector I check all the new players (2019) for new cards added. Exceple Stanley Morgan Jr. I updated him a few days ago and now he has 50+ more cards I do not have on my want list. I will verify I have them listed on my excel file and then add them. NO problem
My issue is some of the other players get cards added to their list as new check lists are added. Exceple Roger Craigs 1988 football Topps stickers (VAR) If I do not check all his cards I may miss one. I could just not look and do the pull down and add all missing cards but there are a few I do not want and I'm trying to keep my excel file updated also.
My excel count and here never matches as there are cards that are not listed here yet.
Wish there was an easier way but I can live with it.
