I emailed this suggestion to support but thought I'd post here to see if anyone else has the same issue/desire.
I collect Amazing Spider-man and due to the modern day trend that society will not jump on a long running title with a "big" number, publishers decided to create new volumes/series with new numbering. ASM has Volume 1,2, Series 3,4,5,6, Superior Spider-Man (V1) and ASM: Renew your vows all in its legacy numbering scheme. Therefore, to create a want list (Items Checklist) I must select those titles each time I want to create an updated list. I think it would be very convenient if a user could create a list of titles and be able to select that title grouping to get all the titles instead of having to individually select them each time.
Some may find it convenient to have multiple title lists such as a Batman group, Superman, Thor, etc.
Anyone think this is a good idea?
