Building set back - how to do in CMv2?

[markshot]

In CMBB/CMAK, you might position a squad or HMG in a building on the far wall, but firing out across the room.  Why?  Well, although narrowing the LOS of the HMG is made the HMG less noticeable to other units.  Also, if you wanted a squad to mainly ambush those who approached the building closely, you set them further back.  (also used a covered arc)

 

However, in CMv2, units gravitate to windows of whatever direction they want to shoot out of.  Any way to achieve the above?  Any reason to achieve the above?

 

Thanks.

I tried using 180 degree arcs towards the "rear" wall so the units would end up against the rear wall.  Then change the arc to the side you want them to fire out of.  Maybe works in a short arc ambush situation.  But, generally as soon as the troops see or fire at an enemy, they all rush over to the wall/window closest to the enemy.

Yeah, and this last behaviour can be a nightmare for crew-served weapons, because sometimes, if they can't fire at a target they're supposed to consider valid, they'll displace within the building, triggering the "extra setup time for being in buildings", even though they would, if outside and moving such a short distance, be "moving set-up" and have a minimal time to transition between moving and deployed. This can mean the weapon doesn't deploy in time to engage the target usefully.
