Open XML SDK 2.0 is used in creating the underlying XML that makes up an Excel, Word, or PowerPoint file. The functionality you are seeking is part of the Excel program and is not achievable through XML.

If you are sending the file back to the user to be downloaded they can choose where to save it from there.
