You can add a table to the backend using the transferdatabase method.
Use something like:
DoCmd.TransferDatabase acExport, "Microsoft Access", "c:\Fullpathwithextensionofbackend", acTable, "Tbl_NewTable", "Tbl_NewTable", False
The first reference to Tbl_NewTable is the table you wish to transfer. The second reference to Tbl_NewTable is the name which you want the table to be known as in the destination db.
The False refers to StructureOnly (thus False transfers data also) - you choose the option that suits.
As far as relinking, create the new frontend with the link already established.
