Thanks to everyone for trying to help

After careful consideration at the weekend --I have given up !!!!
LOL

I think the only answer is to get a 6 switch pedal for the fills but it would have been so much easier if i could have assigned the fills to my Pk5 floorboard
Oh Well, its not all bad i guess and we have AJs upgrade to look forward to now--wonder if its available yet?

Take care guys
