Dynamic column based on slicer selection

Hi,

I have a requirement where we want the users to have the flexibility to change the level of dimension dynamically.

Suppose we have dimension as below and Marks is the measure.

Department

Student

Class

Marks

Now, all the above dimension should be selected from the slicer. If the user selects Department , data should be aggregated by Marks and when user selects  department and Student then marks should be aggregated at Department and Student level. The view should look like as below

Thanks
