6. Double-click the rels folder within the ZIP file. This folder contains one file, .rels.
7. Drag the .rels file to a location outside of the ZIP file (your Desktop, for example).

9. Add the following line to the .rels file, before the tag:
10. Drag the .rels file back into the ZIP file, overwriting the original version.
11. Remove the .zip extension so that the file is back to its original name: change case.xlam.

should be available to simplify this task. Try searching the Web for office custom UI editor.
