Ok so I was fiddling and I can't remember did some of the more expensive animated shop configurations allow for 4 animated textures? I know I used 2 animated textures quite often, but on some things could you use 4?
If you can recall that do any of your remember which specs allowed for what?
I'm at work right now so I can't run it to bring up the specs you are looking for the Shop 6, but this should give you the specs for this and other configurations too. IMHO, it should be part of every Developer's toolkit!
