HOW are you going from the Qu to the DAW?
LR mix matrix USB other ?
Best way for you to record is to use a mix_out into an audio interface to the PC then into the DAW.
When you push the mix select button you can adjust any fader input, or other processing in the mix, including output level from all.
If you have been recording LR then any changes will affect the house sound so you need to use a mix separate from LR.
You need a mix or maybe a matrix out to record in the DAW.
Alternatively you could record to the Qudrive and sneaker net it to the DAW.
If you want all channels for mixing in the DAW then you would need the usb approach or the QuDrive.
