Adding ARRANGER tag

Is it possible to add an ARRANGER tag, for example for a piece that's by Manuel Ponce, with Jascha Heifetz as the arranger?

Many thanks!

You can add more or less any field name to the tag in ID3V2.3ff.
Here is a list of standard fields as defined in the ID standard:
Here is a list of fields supported by MP3tag.
I would think that the "arranged by" would be a good token for the field "involved people" (Tag Field Mappings – Mp3tag Documentation)
"Arranger" BTW is then no standard field and will most likely be not recognized by any player.
