I would like a plug-in for my server / domination plug-in

Hello I am the manager of the 2Fort 1 server this is a mostly vanilla server. I would like a plug-in that keeps domination's when a player switches teams or switches into spectator they lose the domination it is practically the same for csgo I would like if the domination's stayed even if you switched teams at least until you have left. Here is a better explanation of the domination and how it works https://wiki.teamfortress.com/wiki/Domination

I don't know what else to put since this is my first request but please dm me at @Frank.D#4426
