You could set an inherited channel variable as the first thing you do before 
calling MixMonitor(). Something like:

exten => s,1,Verbose(2,Starting Call Recording)   ; I always start my first 
priority with something innocuous
exten => s,n,GotoIf($[${EXISTS(${CALL_RECORDED})}]?skip_rec_start)
exten => s,n,Set(__CALL_RECORDED=1)
exten => s,n,MixMonitor(${UNIQUEID}.wav,b)
exten => s,n(skip_rec_start),Verbose(2,Call recording already enabled)
exten => s,n,...


Something like that may work.
