Dynatable/View - in combobox search show duplicates only once

If I search an element like Local Currency "LC" and the element is in multiple hierarchies then it will be shown multiple times.

Please show it only once. Same goes for all other elements. If I search for a specific Cost center I want to view it once and not multiple times even if it is in multiple hierarchies "Cost center by department", "Cost center by functional areas". It is still the same element. It exists only once.
