Is there a way to use DimensionOverride formula with multiple selections?

Hello Experts,

I was hoping you could help with a challenge I am facing using the EPM for Excel. So within our Model we have the Entity and Employee dimensions.  Each Employee member has a property that ties to Entity.  Currently in one report when a user selects the Entity, we have a =EPMDimensionOverride( formula to only select Employees who have that Entity as a property.  It works fine for one Entity, but is it possible to do something similar if multiple Entities are selected?  I would want it to look something like the image below, where the Employee Dim is nested inside the Entity Dim.

Any advice is appreciated.

Thanks,

Sean
