That's a little bit confusing, but may work... Do you see other possibilities here?

Depenent on some public variable or setting, you open usual or "Arch" set of tables with corresponding aliases as a main tables ("Jobs" alias), and additinal tables into which you will copy records is opened as "Arch" set. You just switch between them. :-)

If it's not broken, fix it until it is.
