uTrack 24 global mixer levels

Hey fellas.
I recently upgraded from an LP16 + a small analogue mixer to the uTrack24.

The product is great, however I am having some trouble with the in-built mixer function. The thing is, I want to set and save a global volume level for each channel, but as far as I have concluded, the only way to use the mixer is by doing track specific mixing either from the front panel of the uTrack or through uTool.

Is there a way to set global mixer settings, so that i.e. channel 1 is at a constant volume relative to channel 2,3,4 etc?

My setup is like this:
Channel 1 for metronome (a .wav that is sync’d to each song, it goes to my in-ears only).
Channel 2 for subkicks, output to the PA.
Channel 3 for Left backtrack, output to the PA.
Channel 4 for Right backtrack, output to the PA.
Channel 5 is meant for monitor send from the soundman (input to the uTrack).

I have yet to test the uTrack live, and I fear that I will need to adjust the monitor send from the soundman for each individual track, which is going to be a bit of a hassle during short changeovers.

What I need is an option to level each channel, so that they stay at the same relative level to each other at all times (if possible, even with changing setlists/tunes imported to the uTrack). Or at least an easier way of leveling the channels, so I don’t have to do it song-specifically.

I hope you catch my drift, and if not then please let me know how I can elaborate!

All the best,
Nikolaj (and the band CABAL from Denmark).
