May I request the addition of arranger field when I add a score? (Perhaps between the Editor and File/Image Type fields) Otherwise I often have to edit the work page afterwords.
Incidentally after I click on Add Score from a work page I obtain an Add File questionnaire.
It's easier than that. All you have to do as add: |Arranger={{LinkArr|Firstname|Lastname}} in the editor field when uploading. Same goes for the Translator and Language supplemental fields
Yes, that syntax is technically correct and should work. If you were going to edit the page anyway I'd suggest getting rid of the |Editor= bit just for clarity, but for the submission page that's fine.
