it would be very nice to have the ability to do a proper room clearing
there for we need the ability in editor to lock doors,

SITUATION :

opfor has captured mr X, mr Y and mr Z they are being held hostage inside a building somewhere on altis our job is to free the hostage and disable all threats.

we get there, doors are locked and only two ways to enter the building but... the doors are barricaded or locked.
now to keep the element of surprise we have shaped charges which only blow up the door or window (not the whole building) and we can do a simultaneous attack on the front and the back of a given building.
