assign Midi Controller (keyrig 25) for Logic EQ

Hi,
I have had a Midi Controller - M-audio Keyrig 25 which has 8 Knobs and 8 Buttons could be assigned.

I wish to make use of those Knobs and Buttons to control each frequency band, as well as the gain (of frequency) and Q-factor. I was successfully assigned those knobs to each frequency band by created a mode for each frequency (e.g: Low Cut mode 1, Low Shelf mode 2, Low mode 3...), then 3 knobs assigned for each frequency control (Knob 1=Frequency, Knob 2=Gain, Knob 3=Q-factor).

Question:

Am I possible to (I've tried but failed) assign those 8 Buttons (C12 - C19) for each Frequency Selection? e.g: Button C12 for Low Cut selection, C13 for Hi Shelf selection, C14 for Low selection...

Your advices and guidances are appreciated! ( ** I can find nothing related youtube tutorial, therefore I post my question here).
