No. All pattern PWPs (signs, standess, etc.) behave exactly the same. The building list has information about X,Y info for every building. Additional info like the pattern used is stored somewhere else (it should be easy to find it though). That info is probably tied to the PWP coordinates. That's why moving them resets them to the first pattern of custom PWPs.im having a problem with the custom design sign pwp, i have 3 of them and whenever i put a design on the standee it's the same design for all 3 i can't select individual designs. i think it has to do with the fact that the design signs are all labeled the same thing in the ram editor? idk
I guess it may be a good idea to disable moving these kind of PWPs until we manage to find how they really work.
