New to Minimserver - a few questions

[realmassy]

Another new user here, I thought was a good idea not to open a new thread.
So, I'm evaluating MinimServer with a Linn DS. Currently using JRiver Upnp server because I've been using it in the last few years as my player (used to have a USB dac before the DS)
I'd like to switch to MinimServer to use a cheap plug computer rather than a full Atom board.
But I'm struggling to browse my music library as I used to do with JRiver: in JRiver I've created some custom views and I can not replicate them in MinimServer. For example, I browse my library by:

Code:

Composer --> Genre --> Work Title (custom tag) --> Artist/Year

In this way I can choose

Code:

Beethoven, Chamber Music, String Quartet No. 12, Quartetto Italiano, 1972

I've also got another custom tag called 'Grouping' which groups different works into the same Opus.

Code:

Beethoven --> Chamber Music -->String Quartets Op. 18, String Quartet in F major -->  Quartetto Italiano, 1972

Can i have something like this with MinimServer? In MinimServer I've have to choose the 'Genre' folder under 'Composer' to display all the genres for examples, which makes the browsing a bit 'convoluted'

Thanks in advance for your help,
Massi
