Softkey for turning on/off EXT IP to PAFL

In studio situation I’m using the EXT IP to PAFL feature for a talkback from the recording room to the mixing room.
It would be great if the feature could be turned on / off with a softkey, so when the artist is playing I don’t get the sound from the talkback mic.

Always entering the setup menu is annyoing.

Or are there any other suggestions for that?

Best regards,
Dieter
