Making a Brush Clip One Team

Im making my second map, ultiduo_rebar (currently rc2), and I'm having an issue with my spawn doors. If a blue team member holds the door open, red team players can walk right in. The trigger is only affected by blue, but red can still get in. Is there any way to make a brush clip one team (in my example, red team) so that they can't get in?

thank you!
that was an incredibly fast response
