How to create multiple running headers in a single multi-page file

I would like to create a template for a document which will have an introductory page and a series of mini-chapters.

I would like the introductory page to have its own running header, and each subsequent mini-chapter to have its own running header.

I am not sure how to do this.

Would I create a series of Master Pages (each with its own running header), one for the introduction and one for each mini-chapter, with each mini-chapter starting on a righthand page?

If the text variable name for each required runnung header was different, could I still draw on a common paragraph style?

Thanks in advance.
