[KoboGlo] Require Character After Z For Sorting

Surely this must have come up before...just can't find any previous threads on it. I use Kobo Utilities with Calibre to create Collections on my GloHD (for some of you, your reader calls them Shelves). I manage all collections via Calibre...none on the reader directly. I love the add-on.

I need to create (in Calibre) a "special" collection that will sort last on the reader when created (after "Z"). Any special (decent looking) leading character will do. Something that looks like a dash/tilde/asterisk etc is fine with me.

This character would need to work fine with Calibre, Kobo Utilities and the GloHD of course.

Thanks.
