This should be possible in the channel mixer dialog (button on the
sidebar).
I also plan a right-mouse-button menu for each slider which would allow
to open the channel mixer dialog directly.

I'll try to implement at least a -D option for the next release.
A ctl selection may be a bit trickier though since some ctl entries may
require arguments.
