Was wondering if it’s possible to add more than one series group for some comics? For example there are multiple issues of Tales Of Suspense that feature stories for both Iron Man and Captain America and I’d love to apply the issues to both series groups rather than just “Tales Of Suspense”. Same with some old World’s Finest that feature Superman and Batman in separate stories, Tales To Astonish with The Hulk / Giant-Man & Wasp / Sub-Mariner, etc.
It’s not possible to have a series be part of multiple Series Groups I’m afraid. The field structure (currently) does not allow this. I’ve taken note of your request.
