Combine Paginated and Desktop reports

I am working on recreating existing reports in Power BI.  In the current reporting tool, the end users are used to seeing the different report types (Excel, PDF, Dashboard) as separate tabs under one report.  I have created a dashboard in Power BI Desktop, and a paginated report in Power BI Report Builder.  My questions is, how can these files be combined?  More importantly, how do you pass the parameters between the different reports (ideally from the PBIX file to the RDL files)?  It's possible to have up to 6 paginated reports under one main report, and users will not want to input the same filters in each file. 

Thanks for any advice!
