CFX file from TotalFlow and historical data backfill

Ignition 8.1.2
Is it possible to use the CFX files from a TotalFlow meter to backfill historical data?
We have a 14 hour gap in meter data where the store and forward data did not work, but we do have CFX files for this data.

Although it is currently missing from the 8.1 documentation, system.tag.storeTagHistory is still available. (It was deprecated in v8, but will be un-deprecated soon, IIUC.)

You’ll have to write a script to read the CFX files and feed the content to this function.
