I really like the new feature that shows the quantity of a particular card rather than having the same card listed multiple times in my trade inventory. With that said I would like to update some of the brands / years where I have multiple lines of the same card to a single line / quantity. Is there a tip or trick to update my inventory, by set, from multiple line items for duplicate cards to quantity without having to delete and/or adjust manually?
Example: I have over 2600 cards in my for-sale trade list for 2010 Topps and within that number the majority of them I have 10 or more times, so having them in a single line format with a quantity would make navigating through them in the trade matching report a lot easier. As if now it looks like I am going to have to remove them line by line and then ad multiples to get them to appear on one line with a total quantity available.
I've already tried moving the cards from one collection to another and removing them from the for sale trade list and then add them back in using the add all cards that are duplicate, but that left them excactly them in the same multi line inventory look.
