The only supported case (for now) is when custom viz slicer is using one data field. it is a limitation and we are working on it.

Thanks for the feedback – we have this in our plans for the service and a future release of Power BI Report Server. I will update the status as soon as we’ve started work on this highly requested feature!LevAjar commented
Awaiting for this feature to be part of the product.
