Full path within a limited group of pages

[#1]

I would like to see movement from page to page within a group of pages within  my website.   Ideally, I'd use the Paths --> Pages -->  Full Paths    report   but limit it  to a group of pages by building a segment to only show me movement among them   (ignore extraneous pages) .   Alternatively,  starting  my full path report with some specific page within a visit,    not at the entry page,  would allow me to zero in to user behavior around a difficult process step.

Need more info ???   -  I'm happy to give specific examples.
