Mikey: Short of re-wiring an existing (TechNote) multi- pedal unit designed for another kb, as I did (see pics below), I too recommend the add-on attachable type units DNJ & ScottL recommended. It's IMPORTANT to note though that they come in either of two ways: "latched" or "unlatched". Be sure to get the "un-latched" momentary switch version. The Roland brand you want is the: Boss FS-5U.
Take notice (in my pics below) of the plywood platform I created which solidly locks it to my Quicklok X-stand and the plywood tabs which surround the pedal unit to keep it fixed and stable from becoming kicked out of place:
