MusicLab guitars have articulations and comes with a pattern library and you can create custom patterns.
I will let Rusty post in the wishlist.

In RapidComposer I can create keyswitch map for all the articulations any instruments, below I'm using Ample Bass Guitar then you just right click on the note and it will set it to any articulation, so you can save the midi phrases with the articulations and they will fit any chord section any octave but still retain the keyswitches.
