Linking between Filters in different Tabs

I have an idea that I want to use a chart and a selection/filter block in a SharePoint Modern Page. The page is set up as 2/3 + 1/3 and I have the PBI chart in the 2/3 bit with the Filter Block in the 1/3 bit on the right (as per the enclosed pic). I have tried using filters which link across pages in Power BI and these do filter the Chart - but if I save these as 2 separate pages - Embedding the same link into SharePoint (as generated by the Power BI Service) and then place Page 1 (the chart) into the 2/3 webpart space and Page 2 (the filters) into the 1/3 webpart space these don't talk to each other. I was just trying to avoid putting all into 1 whole page width webpart space as this means the filter writing will have to be created large for ease of viewing which might look a bit odd on the chart. 

Any ideas would be appreciated. Thanks
