Boy, that must have been a pain back in the days of handsetting type...The hand-press era had all sorts of labour-saving methods. One of them was the use of skeleton formes. After a page of type had been printed off, the pieces of type in the body were redistributed, but the headlines were saved and re-used for subsequent pages as part of the skeleton forme. If you look carefully at the headlines in books printed in the hand-press period, you can sometimes see this for yourself, especially if there's broken type or other oddities involved.
Many books contain headlines—made up of such elements as running-titles, rules, chapter numbers, and the like—at the head of the text-block on each page; and when the bulk of their content remains the same from page to page, printers sensibly held them in standing type for reuse. A set of such headlines for a single forme (two for folio, four for quarto, and so on) and any other material to be repeated on each page (like box-rules), all ready for new type-pages to be combined with them, is called by bibliographers a "skeleton-forme." .... The pattern of skeleton-forme use is a basic fact about the printing of a book. If, for instance, the same set of headlines recurs in a number of consecutive formes (and if no other set is repeated), the book was printed with one skeleton; but if two different sets recur (as when one set is used for inner formes and another for outer), two-skeleton printing was employed. It is not difficult, in many pre-1700 books and some later ones, to recognize a particular setting of a running-title when it reappears, for each one may have identifying characteristics such as broken types, distinctive spacings (not only within the title but also between its ends and the left and right type-page margins), or type-styles and spellings that do not reappear in other running titles.G.

You could manually change the header for each page of course.
Or, come to think of it, in OO, you could define a "chapter" heading style that is the same as your text style, apply that style to the keywords in the text, and then in your header choose insert>fields>other and select "Chapter" and Name. This should insert the text selected. I've done this with long documents to make each page's running header display what section it's in.
