Is it possible to have a 1-sided CTF map?

Like say there's only 1 Intel (Blue), and the Blue team has to defend it against the Red team taking it for a set amount of time. Blue wins if they prevent Red from capping 3 times within set time, Red wins if they do make 3 caps within set time.

Kinda like Dustbowl/Gravelpit, only with flags

Sounds easy enough. You set up the Blu intel and Red capture zone like normal. Then you're going to add the entity game_end. Set it to fire after however much time you want for the Blu win. And Red win would just be a normal ctf thing.
