Make it possible to filter the all recurring actions grid to contain ONLY active recurring actions

I would like the option to be able to filter the Recurring Actions Definitions grid to include ONLY active recurring actions.  

The easiest way to make this possible might be to fix the filtering options for the "End" column.   I know I can add the "End" column to my grid, but that column cannot be filtered as a date column....meaning the filter options do not allow for "Is before" OR "Is after" a given date.  The current filtering options are only text-type options, "Is equal to", "contains", "starts with" ...etc.

As things are now, when we look at all our recurring actions, ALL recurring actions are included on the grid, whether they have and end date or not.  While their "Next Occurrence" field LOOKS blank on the grid, we cannot filter the grid on "Is Not Blank" as Junxure doesn't see it as blank.
