Not sure I fully understand, but I think you re after a searchable database.
I personally think organisation in philately is an overlooked necessity.
Being new to United states collecting, I found this discipline also a bit awkward. (partly through ignorance)
I only have a few precancels, possibly around 500,
what I did was to scan each, then offer Cat# Scott "Type" then Location, in the scan's text string.
So if a Type#277 came across my desk, I just did a global search under precancels to see if I had the item, or a new type.
I've yet to find a decent Album Page that suits, I don't find Steiner really suits.
Welcome any suggestions.
