Custom menu - show albums with a particular length?

[benshepherd]

Hi,

Is it possible to create a menu entry in the tagnavi_custom.config file that would sort or filter by the total length of albums? For instance, I'd like to choose between albums that are, say, between 55 and 65 minutes long. I've looked at the help for customising this file, and I can't see anything obvious that could be adapted to do that. Anyone got any bright ideas?

Thanks

Ben
