Midi Mapping Set/toggle

I’ve been mapping various buttons on my Oxygen25 to Renoise (not many to choose from; mostly transport controls) and I’m having trouble with the pattern loop on/off button – in the MIDI mapping list it’s defined as [Set] rather than [Toggle] which means I have to hold the button down and is therefore of no use whatsoever; is there a way of changing it to [Toggle]?

There is both a [Set] and a [Toggle] option for Loop Pattern in the list.

Thanks. Boy, do I feel silly. :D
