You don't need a LCD screen or anything expensive.  Here's how a universal can work:  When the officer wants to adjust a TV, he first presses one of the digit buttons -- 1,2,3,4, or 5 to indicate the room he is in.  Then he would press Power, Vol, etc.

Get a RCRN08G (<$20).   Use the original remotes to teach the RCRN08G.  Use 5 different device buttons so that each TV's remote signals are taught onto its own device button.   Then assign a single step macro to the digit buttons 1 through 5.  For example if you've taught the Power, Volume and channel commands corresponding to the TV in Room C in the OARN08G's DVR mode, assign a macro containing just one button press to button 3.  The button press in the macro should be DVR.

In this way, when the officer presses 3, the RCRN08G will switch to the DVR mode and the learned signals for the TV in Room C will be active.  He can then adjust the TV.
