Ion xe20 map fader to channel?


Is there a way to map a set of faders to channels one-to-one on the Ion xe20?  We have 96 dimmers and I would like to map the first 96 faders directly to the channels for those dimmers.

I have tried this by having a submaster per channel but that doesn't seem to work (unless there is something I am missing) - for example if I have Ch1 at 50 and that same channel on a submaster, I can increase above 50 with the submaster, but I can't reduce, presumably because of HTP, but I can't find settings that wil give the fader complete control over the channel.

I appreciate I could use direct selects or magic sheet as an alternative.

Any advice much appreciated.
