A master filter for multiple datasets within a published apps

Hi all, 

I have created an app that consisted of 4 datasets . 
The app would show four different reports (which are originated from 4 different power bi desktop files). 
However ,these four files use same header filter across all pages
(FYI , The table for the header filters of these 4 report is also from the same SQL table) .

Is it possible to create a master filter that can controls these 4 dataset within the published app? 
Now users have to manually adjust the filter 4 times when they want to change the same settings for these 4 reports. 

I do not want to build these 4 power bi desktop file into 1 power bi desktop file. 
I would love to keep the idea of 4 seperate report but just wish there is a filter that can apply to 4 reports at the same time. 
Does Power BI support that? 

Thanks guys!
