I've often re-purposed the SIDE match division as the "non-compliant cheating guns" division or some such.  But have sometimes used it for a side match.

With the 2013 rulebook, a "Not For Competition" division has been added.  You can rename the division title if needed.

 

As with SIDE, you enable the division on the setup screen for the match.  Unlike with SIDE, you don't specify stages and strings separately - NFC always uses the same as the "real" match divisions.

 

 

Then, when registering a shooter, you just choose NFC.
