Make remote control one STB Only


From my living room, I am in line of sight of my kitchen set top box.  Sometimes when I switch on the living room STB, change channels, etc., it also controls the kitchen one.  I then run out of HD channels, if one is already being recorded.  There is no way to move the boxes and keep it convenient.

Other TV providers (Bell & Shaw Direct, for sure) have different command sets programmable in the remotes so that they can only control one STB.  Is there any way to make the Optik remotes like this?  I can't find any information on this and it seems like a basic function that has been overlooked.
