trigger_remove

I’ve recently finished one of my maps that I will be using for DarkRP. I have a shabby spawn zone that is protected by a trigger_remove to remove all entities and props (not including clients, lights, spirtes, etc.)

The resolution that I need comes from when you put any entity in the trigger_remove (such as a money printer or a weapon) it will disappear.
I need some way to white list Gmod entities, or specifically DarkRP entities from being removed from the trigger_remove. Some sort of output or input from a point_servercommand or anything would be of help.

-Thanks in advanced

Try different filters, but doubt that wont work.
