How to maintain a single drop-down option(page dimension) for multiple grids in HFR?

Summary:

We have created a HFR report with three grids. Each grid has the same dimension in page POV with same range. Is there any option which will allow us to have a single drop down for the entire report instead of three dropdowns (one for each grid)? The expectation is that the user will select a member from the drop down and all three grids need to get refreshed automatically. Please let us know if this option is feasible in HFR.
