Modding a Meris Preset switch to work with MC8

I was thinking that the Meris Preset Switch, which has 4 buttons, would be perfect to use with the MC8 for Bank Up / Bank Down / Toggle Page / Tap Tempo.

Would it be posssible to modify it to cover all those 4 fuctions using one single TRS cable into one of the omniports? If so, how could it be done?

Strangely enough the two of them work together out of the box. If you connect the Meris Preset Switch to an omniport configured as Fixed Sw 1, one of the buttons will do nothing, another will bank up, and the two others will toggle page.
