Multisampled drums: buttons to overlap samples

I've been trying out the demo version for a while now and decided to order this wonderful product.
What I really like is the way multisampled drums are handled, with the ability to crossfade between velocity layers.
One very simple thing would make doing this much easier tho: the ability to increase the high velocity and decrease the low velocity of the selected layers by one button (+) and vice versa with another (-).

Maybe this could also be accomplished by a modifier key. For example:

Hold alt and click/drag layer up/down -> increase/decrease velocity range of the zone.

I also noticed that many of the preset multisampled drums have curved velocity mappings.

It would be nice to be able to select the strength of the curve when using the "stack zones" command.
