you cant upload vpks, but I think you could call to change level, as-long as the player has that map downloaded aswell, although the workshop does handle maps and directories differently in the PTI, I suppose the only way to really know for sure is to try it out yourself 
Ok, so make it as if a normal portal 2 map with level changes and whatnot, and have a logic relay, but that only get triggered if you let's say no clip into a separate inaccessible room?
Jeess! The uploader is really demanding! And also, for some reason VPKs work for my mac, but not my PC, and I put the VPKs in my maps folder and they work! Whatdafuq is all that schanizel about?
