If I’m writing an historical work, is there a way for me to note the then-current year in the header? It would essentially have to be a header that can be batch-changed or on an individual basis, not automatically increasing at a flat rate. I’ve included an example of what I am attempting to reference (the date can be seen in the upper-right corner).
On a related note, these types of books will mark a new year in the margins, I am also curious if there is a way to do this, apologies if any of this is obvious and thank you in advance!
