Replacing a Compound wall and it is in wrong direction

I have  used schematic CMU to create a building.

We are now updating the schematic walls with real walls..

Where I have a Split-Faced Block (texture is always side only)

I create a nice wall with two parts so that you know which side is rough side

If I draw to the right it is on the top and draw to the left on the bottom

so far so good

The problem is when I replace the existing wall with the New wall

Sometimes the are correct and some time the wall are flipped - in hte wrong direction

It all depends on how the wall was origianlly placed.  

HOW DO I CHANG ETHE DIRECTION OF THE WALL SO THAT THE ROUGH SIDE IS ON THE CORRECT SIDE

My work around is to have to walls - one for lefty and one for righty  - but now I am not BIM compliant as it messes with a take-off of materials
