running subreports without breaks in between

Hi.  We run 2012 enterprise.  Can subreports be called from a master but be presented (at least in the browser) without any kind of break (page or otherwise) or gap between subreports?  I'm looking for a scrolling effect where all subreports look like one big scrollable report and each subreport represents just another "section" with its own section heading.  At least one of my sections has to be a matrix because of its variable number of rows.   I may need some Drill Down (ie expand collapse behavior) in some sections.  There will be no drill thru required in this particular project.
