It would be great if we could create hierarchy between filters.

For example, I have a table called impact area, which is joined via lookup to a much larger table called impact topic. I would like to create both table filters, but associate them in such a way that if I select a value within impact area (say, Governance) the Impact Topic filter would only display to the user the values that look up to that Impact Area value (The Impact Topics under the Governance Impact Area). 

This would essentially make the values in a filter contingent on the selection from another filter, in cases where there is a logical hierarchy between them in the database
