Wish: insert same file as independent blocks


example: I have a train with a first class seat. I need this seat at different places with a light different look, some little parts on layers need to be turned on/off. I insert the files named as “block a” and “block b”. But I don’t get independent blocks with two insertions at the layer manager.
Could this be added to v6? Maybe it’s not so difficult to add. So, we could get different “configurations” of one linked block file. At the moment I need to save an extra copied file for each configuration.

(The very easy to use old Pro/Desktop from PTC allowed to setup configurations of one linked file for assembly use. It was a great feature.)
