I was printing some Collection Overview reports and was looking at Action Comics and noticed once the /A variations began, issues no longer aggregated, they simply enumerated.
Rather than have Issue # - Issue #, it listed them individually. For some long-running series that will become a pain.
I understand that for most there is a "regular" issue # and an /A variant, which makes this difficult, but I think there need to be a rethink and redefinition of what a "regular" issue is. You cannot have a system that uses the concept of "regular" issue and then stop using it.
For me, and I am being a bit selfish here, I rarely get variants and I would prefer them to be subsheeted or sublined underneath a particular issue.
For example, each issue should have a parent stub - Action Comics 1056 for example, that's the "regular" issue. Underneath that stub (or parent) are the covers. Whatever numbers in the sublines is summed in the stub. This way each issue will only ever have 1 stub/parent and have X lines for covers (regular, variant, whatever). If you want to view only the stubs on a grid, you can. If you want to expand to add information like quantity, you can. I vastly prefer this solution as it makes the grids much more browsable.
