Filter FLAC tracks by samplerate, samplesize

Hi,

It seems LMS stores sample rate & size for FLAC tracks in library.db tracks table.
Is there any way to create a new category (for example, HD Tracks that would return only tracks with samplerate > 44100 or samplesize > 16).
Atm, I have not found any way to achieve this with stock LMS (7.9.2) or even using "Custom Browse" plugin.
Any idea on this subject, anyone ?

Regards

Éric
