Monitor file from mixmon in AMI as CDR custom field

[Smitellos]

Hello everyone.
Im trying to get monitor file variable created by mixmonitor being visible in CDR AMI console.
Is there a way to assign it not to one extention, but to all extentions i have? Something similar to this:

exten => _X.,n,Set(CDR(userfield)=audio:${CALLFILENAME}.${MIXMON_FORMAT})

freebpx ver 14.0.10.3, asterisk 16.3.0
