Please fix sniping by same team

The sniping issue was fixed with people for members of other teams that would wait for a gym to fall, then claim it. However, its happened far too often where I will level up my teams gym, and someone waits until I do it and they put their Pokémon in.
This isnt a big issue but it can be extremely frustrating when youre the one battling for a long time, and then someone else takes the spot. Please make it so that only the people who level up their own teams gym can put in Pokémon. It would prevent freeloaders and if they help level it up, then theyre also allowed to claim the spot.
