Insert side page marker

I wanted to know if it is possible and if yes, how can I insert some sort of page marker. I don’t know exactly how it’s called…
I’d like to have like a rectangle or any sort of shape that would get printed on the page side to indicate the section/chapter (see joint example). Best would be that size gets adjusted based on the number of chapter and that it progressively jump down from one chapter to the next one.
Thanks for your help!

You’ll need a fully fledged page-layout program like InDesign for that sort of thing (Someone’s going to correct me and say you can do it in Word! :slight_smile: ). You certainly can’t do it in Scrivener.
