You can use the transfer spreadsheet macro and specify the worksheet as part of the range function, see below, taken from access help.
"The range of cells to import or link. Leave this argument blank to import or link the entire spreadsheet. You can type the name of a range in the spreadsheet or specify the range of cells to import or link, such as A1:E25 (note that the A1..E25 syntax does not work in Microsoft Access 97 or Microsoft Access 2000). If you are importing from or linking to a Microsoft Excel version 5.0, 7.0, Excel 8.0, or Excel 2000 worksheet, you can prefix the range with the name of the worksheet and an exclamation point; for example, Budget!A1:C7."
