Please add Baritone and Low G to instruments

Thanks for the great program!
I play ukulele and I"m writing parts for a Baritone ukulele (tuning DGBE)
I found the capo feature so I can hear the parts played together in midi, but I can't change the pitch of the 'high g' string down an octave. I play ukulele with a low G. Could you please add Baritone Ukulele and Low G Ukulele to your instrument choices?
Thanks a bunch! This is so awesome!
