I realise that 'headers' may not be the correct term but... is it possible to apply a series of different 'headers' to different sections in a single document?
In the example where a single document consists of three 'chapters' (say, 10-15 pages each) I'd like to have a 'header' that reads: "This is the first part" at the top of all chapter one pages, "This is the second part" at the top of all chapter two pages and "This is the third part" at the top of all chapter three pages (etc).
I thought this might be possible using a series of master pages but have no idea whether that would work or how to go about it so any clues would be most appreciated - am using latest release of ID (CS6) on Windows 7.
