Delete I/O Timeout from tags during backfill?

We had a connection with a historian run into an issue where it continuously was connecting and disconnecting, and writing I/O timeout every time this happened many, many times. Now during the backfill the trends look odd because there are data points with I/O Timeout between them all.

 

Is there a way to mass delete I/O timeout values from tags? Or a way to overwrite these I/O Timeout values during backfill?

 

Thanks!
