Can you use a custom font in Glance mode?

I think asking it is answering it, but hopefully I'm overlooking something... Thing is I want to use icons in my widget glance view to save space, but using "Ui.loadResource(Rez.Fonts.fontname)"  gives me a "Could not access symbol 'Rez'" error.

Is this really not possible?

And I missed the 'scope' settings with resources, sometimes it's hard to find the proper combination of search words ;)
