I am sure there is, but it will probably be more difficult then copying
that data in the first place. From your previous function there seems to
be lot of moving parts. Unwinding those tables and any other data that
is dependent on those tables could be a chore.

That would depend on why and what you want to restore. The function is
going to need some sort of prompting from the user on what criteria to
use to determine the records to select and restore.

My help would be to say, first sit down and draw out the dependencies
you have between the data and the various tables. Then work out an
outline form of how to walk the data back from those tables into its
original location(s).
