How do I bring up my custom maps in pvp?

[ReSpawn]

I looked around for the answer, couldn't seem to find it. If someone could post a link, it would be much appreciated.
So, I can bring up other peoples custom maps in the "view all maps" portion of the voting menu, but I can't bring up mine unless it's just with bots or solo. If I use "/map mapname", the way I'd load it for editing, it says "invalid vote" durring pvp.
