Disable physgun interactions

Hello, this may seem like a stupid question and I’m sure there’s a simple answer, but after looking and looking I cannot find a result.

Is there a way I can limit the physics gun on a Garry’s mod 13 dedicated server, so that people can only use the physics gun on props/ragdolls/etc. that THEY’VE spawned? It’s terribly frustrating to have people physgun your vehicle while you’re in it…

Awesome thank you!
