Is there to arrange a possibility the contents of a field in alphabetical order?
from:
Gitarre\Kontrabass\Klavier\Saxophon\Viola\Violoncello\Klarinette
to:
Gitarre\Klarinette\Klavier\Kontrabass\Viola\Violoncello\Saxophon
Where do you see this "field"?
In the GENRE tag?
Could you please show us a print screen with an existing example?
BTW: Is this a follow-up question to this Lieblingsinstrumente?
Maybe this existing thread can help you too:
