what I suggesting is having the option of either using the already “track outputs” or a check box in the Samplke Instrument dialog that overrides the track out with “16 sample slot outputs”.
so that reorganising of sounds is no longer an issue to achive professional results when using Renoise in the studio. 
I like to have drum kits made out of the 16 samples that I can have in one Instrument…so that I can have my KICKS, SNARES and HIHATS all on separate outputs without having to program them on different tracks. 
great way to process them Kicks and bass thru a nice Lunchbox or Manley tube before recording to tape (disk).
