Performer W/Instruments Sort

[aspaceintime]

I have been updating tags in my library. I want to be able to sort the Performer tag alphabetically. I have included my current setup in the attached files.

My Performer:Perform W Instruments index is what I'd like sorted by last name.
I can get a partial result using the performer_name_sort: Performer Sort (A-Z) index, which sorts performers by last name, but I lose the instruments.

Is it possible to sort by last name & include the instruments? Any help would be great.
Thanks
