How to repeat section number without incrementing it in Adobe InDesign?

I am styling a document with many sections. The section number needs to be repeated throughout the section (a la running header). However, there is no text variable/marker for the current section number in InDesign. Is there a way to repeat the section number without incrementing it at the same time? I am looking for a solution where the repeated number will automatically change to match the section number, I specifically do not want to have to do it manually.
