Routing and Multiple mixers

Hi, what about to make mixer in uTool based on SENDS? I mean, it would be great to be able to send 1 MONO WAV FILE to any output in different volume.
So for ex.: into output 1 would go tracks 4,5,6….

My example:
Simple bands like my band is would like to use 1 mono output to audience and 1 mono output into inear system. But we want to mix our 16 MONO TRACKS every day in different way: We play sometimes with live BRASS sometimes it is playbacked and more changes… I dont wanna bounce special tracks for every gig from my DAW…

In other hand, if you got 1 monotrack to the audience [mixed from more tracks in your DAW], you realize if it is good sounding mix after few month. Everytime make a new mixdown of my tracks in DAW is very comlicated and time consuming.

Besides the examples above the routing like sends would be nice. Before gig you make a mix in uTools and export to flashdrive. No DAW need for your multitrack songs.

And what about seprated stereo MIX into front headphone output? :]
