Feature Proposal: Expandable/Collapsible Page Sections for Reports on Same Semantic Model

I currently do this with hidden pages and page navigation. 

However, if I am in section 'Executive Summary' and suddenly want to go specifically to page 'Decomposition' in the Agent Analysis 'section', the user has to navigate to the Agent Analysis section via the built in navigation on PBI service, then select the button on the navigation pane. It's a whole new extra step and development. 

Don't even get me started on subsections.
