I want to make a complex, custom titlepage with graphics etc. (I don't see that using the default template is an option). I want to use the "TeX Gyre Pagella" serif font (-> http://www.tug.dk/FontCatalogue/tgpagella/) for the "normal" text and a sans serif font for the title page (maybe also for chapter, section names etc.).
If I load the Gyre Pagella font a sans serif version of this font is also loaded, right? The problem is that I want the title text bold and in sans serif but it doesn't work (I can't get it bold). Is such a case not "defined" in the font definition file? Is it possible to use another sans serif font in Komascript?
