Question concerning custom jerseys.

I know that it was impossible to create an extra jersey for a team in 2k9. I was out of the 2k loop for 2k10. I am wondering if it is possible to create a secondary jersey for a team while keeping every other jersey for that team in the game?

with the REDitor we can switch uniforms from team to team "add" new ones by overwriting blank slots and do a bunch of toher things

Thank you for the information JaoSming!

So is it possible to add the OKC alternate jerseys with the file name ux024.iff? If so how?
