Universal File Loader (UFL) -  How to get Pi Archive to store a "No Data" point?

Flat files are sent to an interface node for UFL to process and send to Pi Data Archive.


Sometimes a sensor stops sending data for a short period.  How do I get a "No Data" or "Interface Down" state to be recorded for the relevant points?   Currently, the Pi Data Archive will simply extrapolate between the last point before the gap to the first point after the gap, even if the gap is hours or days.


I would like to be able configure UFL to load a "No Data" point if no data has been received for a point after a configurable number seconds or minutes.
