Freely assignable AMM groups

Hey guys-
Been doing a lot of corporate work recently and have been relying heavily on AMMs.
The company I work for has a DM7 in our one location but picked up a DM0/C3500 for our new space.
On the DM7, you can freely assign inputs to any of the 5 Dugan groups. Unfortunately on the DM0, while you still get up to 4 groups, you’re fixed to 64, 32, 16 or 8 inputs per group depending upon how many groups you have.
Found this out the hard way when I needed 3 groups (presenters, audience & remote participants) the other day & my main group of presenters had 33 on a panel and needed to freely engage with 4 remote participants and 8 audience mics.

It would be great if A&H could match Yamaha and allow the AMM groups to be freely assigned.
