Thanks for the reply, Marc.
Instances of this are situational, so I’m not sold on a master page object as the answer. (Although I could just apply that master to the pages where I need this, so it may work.) Many of my searches on this topic yielded results about table headers, which was frustrating. Others were for running headers on master pages, so I understand how that works.
I had another document a few weeks ago I wanted to do this on. It was an FAQ, and if the questions & answers were lengthy enough for the topic to run to another page, I wanted to repeat the topic header on the new page. Thinking on it now, a master page with text variable was probably the way to go there. I still feel like there should be another way to do this; please keep the advice coming!
