Rebuild On-The-Fly Headers During/After Testing

[EMR]

I've encountered on several occassions, customers who assign serial numbers / partnumbers during the test process who still wish to do on-the-fly recording.... and are disatisfied with the default behavior of the reporting because their header persists in showing the blanks etc.

While I understand that it's easier to build file paths / headers once, and then append the body content onto them, it would be especially elegant, if there was:

(a) a way for me to manually trigger (via a callback perhaps) a refresh of the entire header or

(b) if at the very least, the header section & file path were overwritten/updated once at the very end.

Since it seems to me that the header has to be re-written at least partially to account for the failure-chain logic, it wouldn't seem that much more work (or that much more inefficient) to just refresh the whole thing?
