Any way to NOT include the schema name when linking tables in Oracle?

I've got an Access database that was converted to a front
end to Oracle tables on the back end.

Short of redoing all the queries/forms/reports and/or
manually reanaming all the tables after they are linked, is
there any way to tell Access NOT to include the schema name
as part of the linked table name when linking tables? For
example, table CUSTOMER in schema INVENTORY gets linked as
INVENTORY_CUSTOMER when I just want it linked as CUSTOMER

Thanks,

Eric
 
I use this procedure to re-create links to Oracle.
There is a local Access table (tblODBCTables) that contains the table names
and primary key fields I want to link to on the Server.
Note: the source table name needs the Schema User prefix which is in the
code. ***The linked table name usually omits this.***
