How about this option, so you can only do eg a +12 on the current instrument, instead of the other options?
This making sense to anyone? 
No it does not make sence, because you can allready do that in the advanced edit… 
Use the checkbox: Filter by source instrument.
Not really the same thing but you can also change the basenote on the Instr settings.
Ok, I got it to work.
Thanks!
