Splitting Artist Tags

I need help splitting artists into separate tags. My tags currently use a forward slash to separate artists (artistA/artistB), but it doesn’t properly separate them in Symfononium. Instead of appearing in both artistA’s and artistB’s discographies, it makes a new “artist” called artistA/artistB and puts it in there.

Is there a way to change this? I know you can set tag separators in the Mange Media Providers section for some providers, but I don’t see that option in the Subsonic provider for my Airsonic Advanced server. Airsonic lets me set genre tag separators, and that worked, in Symfononium, but there’s nothing for the artist tag as far as I can see.

This is to be done server side as the many other posts explains.

I see. Thank you for the clarification!
