Each named range in Excel is a separate table.
You may be able to open a union query against
several 'tables' at the same time: you may be
able to join several 'tables' together (or you
may not...)
Normally when you import, you have a choice of
creating a new table, or appending to an existing
table. Perhaps you need to look at your import
method, and see if you can change it to do append
instead of create.
