My friend and I would like to start a co-op run, could we make a catagory for any% Co-Op?

What difference would co-op make, though? It will basically be the same experience as solo any%

This thread is 3 years old so I don't feel like continuing it. Any% co-op is on the Misc. section on this leaderboard. If you're interested in the differences, just watch a run.
