How to have two cap points unlocked at the same time?

Hey there.

So I'm making a 5cp map (https://tf2maps.net/downloads/cp_tunnel.7975/), and I want it to work like this: whenever the mid point is capped, instead of just one of the 2 red or blu points being unlocked, both are unlocked and available to be capped until the other team gains control of the mid point. Right now I'm using the 5cp template from Boojum's resource pack (cool stuff), but since I'm a noob when it comes to logic and all that I don't really know how anything works. It would be great to get some help on this ASAP since I'm leaving tomorrow for a couple weeks and won't be able to work on the map, and I wouldn't like to leave it with this issue.

Thanks in advance!
