Midi Raider and Expression Pedal Switch Question

If anyone has the Rocktron Midi Raider I am wondering if you can use the Mission SP-1 using both pedal jacks on the Midi Raider so you can control Wah on/off with the switch just like the GCP can? Searched all over with no luck and also emailed Mission and Rocktron but they couldn't give a definite answer if it would definitely work.

Thanks,
