Hi @mattyn07 ,
I am not sure what do you mean, but you just need to append the filter query to Tile URL, there is no need to do anything on Power BI perspective.
If you feel this way is hard to achieve, here is an alternative workaround that you can filter directly on the Tile control.
1. Go to your Power Bi Report in Power Bi Service
2. Click File -> Embed -> Website or portal, and copy the link
3. In Power Apps, Insert -> Chart -> Power Bi Tile (but don't hook it up to any data)
4. Select the tile, and go to the TileUrl Property and paste your link


You can find the Filter Tab is embedded in the Tile. Hope this helps.
