Allow the pre/post buttons to cycle through all the same tap points that are available in the global ip direct out settings, per channel, per aux instead of simply pre/post. Or pergaps add the option to select this in the routing menu. Same with direct out, per channel.
to cycle through the options will slow down the workflow
I think it is better to switch between pre/post only
and have the selection of the point as a setting since this is mostly adjusted before the show
