My question is this.....  In Studio One's  midi editor they have a feature that lets you "humanize" the velocity settings
of an instrument (AD2 in my case) after setting the initial intensity to the same level This is a quick way to correct and set many velocities at one time for things like HH snare or Kick drums. 
 

For AD2, I'd recommend looking at the Beat Transform option with AD2 itself. It has a randomize option, for velocity and timing, but you can also change the interactions of the dynamics of kit piece groups, and how change the focus of the accents. If the midi is alreaddy in the PRV, you can drag it back to AD2 for manipulation, then drag it back to the PRV when you are happy.
