Formating chapter headings with folder section title (Part Heading)

Greetings, new Scrivener user here. And writing my first book. I am struggling with the formatting of chapter heading when I have a section of my book consisting of chapters which they are part of.

I have my manuscript setup with Folder names for the chapter titles (I am not using chapter numbers). For example, normal chapters that are not part of a group look like this:

Chapter name

For chapters that are part of a group I want to see:

Group Name

Chapter Name

I can get the Part Heading to work but they are always appearing on a page by themselves. I have played with the compile and page style setting for several hours and I can not seem to figure it out.

Thank you in advance.

Carl
