Power BI Matrix Dynamic Row Headers

Hi All,

We have a requirement where we want to change the Row headers of a matrix visual based on Slicer selection.

For Example- Consider a table below.

Category, Region, Sales

A              East       100

B              East        200

C              West      400

D              West       500

We want to give a slicer where the two options are Category,Region.

If the User selects Category then the matrix visual shows 

Category     Sales

A                 100

B                  200

C                  400

D                  500

If The User selects Region then

Region       Sales

East            300

West           900

Also is there any possibility then this slicer can be multiselect? For Example show both Category and Region?

Thanks

Sumit
