tagCustom

[stefano_mbp]

just updated to Minimserver2 (Ubuntu 20.04.1)
I'm using Lumin app as control point
In my previous configuration on Minimserver (1) I was using this configuration for tagCustom : all.display.multiTag, Composer.displayRole={artist}
this enabled Lumin app to display in the track details pop up window all the artists one for each row (see attached screenshot)
now tagCustom is gone and I tried to use upnpCustom but this gives an error about wrong value in upnpCustom property.
Is it possible to use again
"all.display.multiTag, Composer.displayRole={artist}"
somewhere?
