Just what I mentioned in the comments.

After thinking about what @TehRealSalt and another users has told me. I could have it so That the two big circle doors in both intel rooms are shut so that only entrence into the intel room is vents and going by the Spawn rooms. But say the Red Team caputres Middle It opens Blus Intel room while Reds stays locked. While Red still has to capture Blu's Intel Room to Open the doors where the intel is.
