This isn't bug but I would like to use.
Bug report Hog4 v1.1.2 b339 Touch and Suck command with wheel
And I thought, Wholehog3 had same command and it was work.

I would like to have hard or pallet value from out put.
So, We are having Touch and Suck command.
However, I couldn't use these command with wheel properly.

Let's do following.

Make iris, zoom and focus pallet separately.
Make cue with using all above pallets.
Play back cue.
Now, I would like to have value one of iris, zoom or focus.
I tried with following procedure.

Hold Touch or Suck button and move wheel that I would like to have value into programmer.
It's bring hard value always. and bring all value after release touch or suck.
But I would like to have pallet value also. and Would like to have only value that on wheel I moved.
Is this a bug? or specification?

I would like to do this.

Thank you for your help and understanding.
