Elektron Musical Instruments

I've been playing with programming chords for the arp and I like it a 
lot! (great job elektron) But I found that it is impossible to 
program chords wich span more key's than one hand can handle since 
you need the other hand to press and hold the trig button. Is there a 
already a trick to hold this trigger so you can use both hands to 
program the chord? Or maybe a way to enter the key's for the chord 
one by one?
