I come back to my post, if the desired functionality is not present in the drop-down "Function" assigned cc#7 ( volume ) , I just checked ... not seen, nor the similar "Glide"!
On the other hand, Glide, like Pitch Ben, is in the Genos pedal options...
Direct Access + pedal from 1~3 , you get to the assignable screen, then in the orange box change the function displayed by the Glide or Pitch Ben and you'll see the settings available at the bottom of the screen!
I put the Glide on a small pedal with polarity when I need it.
For me, it's more interesting to use like this it as it's programmed into registrations from time to time ... on the Mfc10 it's not, it's too rigid, and I prefer the volume for the right hand on the Mfc.
When the solution isn't available ... we go to plan B etc ...
