Index when sorting by last name

[muesli]

Hi,

I like to sort my artists by last name. So I added the AlbumArtistSort tag to my music library (e.g. AlbumArtist = Paul Simon, AlbumArtistSort = Simon, Paul).
By setting tagValue AlbumArtist.value.sort={AlbumArtistSort} everything is sorted as I like
But unfortunately there is a little side effect: Before I made these changes BubbleUPnP showed when scrolling a little popup with the letter where I am at the moment. That does not work any more. And worse: When I want to select an artist by the the remote control of my Naim NDX now I have to scroll all through the library using the "arrow down button". Before I could use the number pad to address the first letter of the artist (like writing SMS on an old phone). That kind of indexing does not work any more.

Maybe someone has an idea of how to solve this? That would be great! I hope I could explain my problem which is not so easily in a foreign language

Thanks and best wishes from Germany,

Volker
