Composition field

I’m a classical music collector so I really appreciate the “Composition field”.
The operas of each composer are categorized in a catalog by alphanumeric and numeric value:
Es. for Bach is BWV 1007 (the first cello suite).
Is it possible to develop the composition field dividing it in 3 field so that compositions are sortable by catalog number?
Following my suggestion on how to do it:
the first for the catalog type (Bwv) the second with a numeric value for the catalog number and the third one for the title/description of the composition
Thank you anyway

I am afraid that is unlikely to happen. I would recommend to come up with your own naming convention in the Compostion field, to make it sort correctly.
