Changing defaults in file requester boxes?

Mac Excel 2011 v14
See attached images. When saving a file in CSV format, the first file requester has "Save" highlighted as default. The second file requester "This workbook has features not supported..." has "CANCEL" highlighted as default, rather than "CONTINUE".

This causes the user to mouse click "continue" which is time consuming for many files.
Is there a way to change the default of this box to "Continue" rather than "Cancel"?

On a related note... the Windows version has "Continue" as default.
