Have you found inserts from other brands (Franklin, Daytimers, etc.) that work in the Coach Agenda? I love the Leather Agenda in Punch, but I need more writing space. I currently use a Franklin Covey 2-page a day system and I think I'd need to replace the pages that the Coach Agenda comes with in order to be happy with it. Has anyone done this, and if so, what system and what size Agenda did you purchase? Thanks!
