How to display headlines in the running title including their automaticly generated section number?

Is it possible to display headlines in the running title from a paragraph style including their automaticly generated section number?

In the menu the variable "Kapitelnummer" (section number) has no relation to a self created paragraph style. With the help of a character style I also don't come to a conclusion.

By the way: The publishing house I work for dosn't except any additional scripts!
