Hi there, if a pedal has more than one switch, it's going to need to have an external switch input to access the second switch. I don't know that pedal, but it doesn't look like it has an external switch jack. With most pedals, it's possible to have the pedal modified to add that jack, but how easy or difficult it is depends on the pedal's design.
If you do have a pedal with that jack, for example JHS pedals that have a "red remote" jack, then you could connect it to one of the function switch outputs on the PBC/10 and control it that way.
