Has anyone had any luck customizing the Print Preview window?

The Arbortext help says it can be done using commands like magbase 1000 in Arbortext's pubview.cf file or by making a docname.vcf in the doctypes directory of the document you want to customize the window for. I have tried everything I can think of (editing the local Arbortext pubview.cf, editing the PE Server's pubview.cf, making the docname.vcf files everywhere I can think of, all to no avail. Has anyone ever done this and had it work or should I contact PTC support? Thanks for any help anyone can give.
