Paginated reports with Pass Through from PowerApps

Morning,

I've created a link from a PowerApps form that allows the user to make a selection and click through to PowerBi, this link carries the filters and applies them to PowerBi as a report level filter.

However, when we try use 'Export to PowerPoint' it doesn't carry those filters and gives you all the data.

So here's where I need your help, here's the options as I see them;

-Can a pass through be created so it physically impacts a filter on the report (the pass through reduces the options within the filter, but doesn't actually tick the box)

-Is there a way to get the filter to actually select the remaining option? (I've tried single select, but this doesn't work, the filter still holds the one that was selected originally and the one in the report level filter)

-Any other ideas how to get Paginated Reports to recognise report level filters? 

^^I think any of these options would resolve my problem.

Thanks.
