Displaying featured artists as "feat. [Name]"

[Spymaster]

When I tag a featured artist, I generally do so as "[Track Artist] feat. [Featured Artist]" Asset UPnP properly divides these artists up and stores them separately. But when displaying those artist details in, for example, Hi-Fi Cast (for Android), they are presented more simply as [Track Artist]; [Featured Artist] - i.e. treated simply as multiple artists, divided by a semi-colon.

Is there a way for featured artists to be displayed specifically as such, with "feat. " preceding their names? If not, please could this feature be added?

Asset isn't my primary server but I've never known it to do that, though I've only very recently switched to 'Artist 1 <collab> Artist 2'.

How are you tagging your music?

I'm tagging with dbPowerAmp for CD rips, and MediaMonkey for final tagging (and digital music tagging), prior to upload to my Synology NAS.

Sorry I meant what tags are you using.

As a test I had Asset index a selection of tracks that had feat./featuring/with/+ in the ARTIST tag and none were split; both the Artist index and the track listing displayed the unmodified tag values e.g. 'Elton John feat. George Michael'.

I've just started using the ARTISTS tag as provided by Picard:

ARTIST: Elton John feat. George Michael
ARTISTS: Elton John; George Michael

Though support is limited it's a more flexible approach.
