Any way to send midi message on QC looper record?

Whilst the QC remains incapable of storing loops internally (come on Neural, this would be an absolute game changer if you implement this) I am having to connect an external looper to give me drum beats etc to then build loops within the QC.

I am therefore trying to trigger the external looper (Boss RC5) to play as I hit record on the QC Looper X.
I’ve mapped the midi function that will select the correct loop on the Boss using the QC ‘On Preset Load’ function and now I want to start the Boss loop playing as I hit the record switch on the QC. I’ve mapped the correct midi function to start/stop the Boss to footswitch E, which is the SAME switch that starts recording in the QC Looper X.
Sadly however the QC doesn’t send a midi message when you’re in the looper page.

Is there any good reason why this should be the case? Has anyone found a workaround for this? Is this worth a feature request? It would be incredibly useful to be able to coordinate external loopers while the QC looper remains so limited in functionality
