There is a registry sub-forum that this would fit better in but be careful offering any criticism of it with the current administrators; most complaints are now told to just create "custom" sets. Before I was banned for disagreeing with the new changes I was given these statements by Mike:
"Be advised that several admins have put a lot of thought and time into this."
"The Registry is a free resource, operating at the discretion of the company, and it is at the company's discretion to make any changes as it sees fit. It is also at the company's discretion as to how and when any changes are announced and implemented."
In short creating separate sets for SS and Universal would be to much work. This also applies to newsstands which have a higher point value when entered, so your Universal direct edition comics are #3 on the tier list.
