About Pocketbook Touch Lux 3 bookshelve support

Hi,

I can manage Kobo Glo bookshelves (Kobo call them collections) by creating custom "collection" column, and entering "#collection" into KoboTouch device settings.

Though I cannot find out how to setup bookshelves for Pocketbook Touch Lux 3 my father owns.

Is it simply not (yet, I hope) supported, or I should search for solution somewhere else, not in device settings?

Thanks.

P.S. thanks for great software, by the way!
