Light editing of a mission on dedicated server

[Catchdog64 11]

So some friends and I have been playing a mission that I've been making, that is hosted on a dedicated server. Problem is, the mission is still wip, and I'm wondering how to edit it without having to change the name of the mission every time. We tried deleting the old pbo from the server and replacing it with a new one, same name, but it didn't reflect any of the changes I made. Any clues?
