Midi buttons to increase/decrease... Is possible?

[Qcontinuum]

Hi all, I'm on resolume 7.13
I work with apc40 mk2 for layers and apc mini for effects control.
In my apc mini setup, sliders controls effects opacity but there are no more potentiometers, only buttons.
Trying to figure out if it's possible to map 2 buttons to increase/decrease effects values (noticed in last update that all sliders now have +and - buttons operable via mouse but not midi mappable).
