Brass Mutes and Unison Playing Techniques

I am using JABB for my playback for brass with mutes. The Expression map for that works fine, triggered by playing techniques. (ie Cup Mute will trigger the key switch E1) I also have a playing technique called Unis. this is mostly an indicator for the live musician to listen and tune with the other trumpets, etc.
My problem is the Unis. playing technique is set to the “Natural” setting and cancels the mute setting.
Is there a way to set a playing technique to “Do Nothing”?
or will I have to create multiple “Unis.” techniques? (Unis w cup, Unis w harmon, Unis w straight, etc)

You can activate the Suppress playback property for the playing technique, perhaps?

I think I have solved it by creating a Playback Technique of DoNothing and then setting the Unis. Playing Technique to use that Playback Technique.
