Is it possible to rollback calculations of a PI Performance equation tag to when the event or source tag is created in PI.?

It is possible, can be achieved with the PI Performance Equations Recalculator. Please check the session "Recalculator manual startup options" at the documentation PI Data Archive Applications User Guide!
You can run manually this utility, ex.:
János Petró has the right solution.
This type of situation is easily handled with the PI Analysis Service and it's backfilling / recalculation capabilities. I just wanted to mention it!
