Suggest that 'DATATYPE' filter only present types from results

[BKLounger]

A search enhancement suggestion: the DATATYPE filter is great. But a search result list may only encompass just a few, or a set number, of possibilities. Could the drop-down filter present only the DATATYPE's from those results, instead of every single possible DATATYPE available in Revit? This might work better as a refinement to existing results.
