Combo button support

[operationflash]

Is there an equivelent of the btn.multiBtnCb(btnA,btnC,dubugCombo_wasPressed) function, as found in UIFlow? I could not find it and using this function directly doesn't work. I tried a few combinations but couldnt find a buildin function for it. Otherwise building it is not a problem, but was wondering if it was supported out of the box.
