As I've already said, you can achieve the same funtionality, without the embedding headaches via hyperlinks to the external files.

Of course, you'll need to figure out what you want to do about the fact you can't have more than one hyperlink per cell. You might, for example, have multiple rows for that particular item, with the cell in each row having a different hyperlink. In that case, of course, you'll need as many rows as the maximum number of hyperlinks. Alternatively, you might prefer to merge the files for that item into just one file.
