Velocity layer setting for all pads simultaneously?

Hello,

I have the following problem, I would like to create a drumkit. Each drumsound of this kit consists of eight layers, each of which has the same volume. Now I have found that Groove Agent 4 has no function with which I can enter the layer volume for all occupied pads at the same time. This can be very time-consuming with 60 sounds.

It would be nice, if this function could be submitted in one of the next updates.

Thank you.
