When I open a workbook in Excel, I can merge another workbook's cell styles into it by pulling down the Cell Styles menu, clicking Merge Styles, and selecting from a list of other open workbooks.

But when I open an Excel worksheet that is embedded in a Word document, it seems to exist in a world of its own. The Merge Styles list is empty, even when other workbooks are open in the "outside world."

Is there some other way I can import styles into an embedded worksheet?
