It would be easier to enter instrument credits for an artist if their previously used instruments and vocals were taken into account.

For example, if artist Semjon Barlas already has credits for the instrument "trumpet", then the next time a user selects him with the relationship type "Instrument", "trumpet" could be highlighted as a recent or suggested item or it could even be filled in automatically, and the same for vocals.

If an artist has multiple instrument or vocal credits, those previously used values could be presented as suggestions, while still allowing the user to enter a new instrument or vocal if needed.
