Adding new line to button's title/description in outlook 2007 ribbon

Question

Hi

I am developing an add-in for Outlook ribbon 2007 using ATL/C++. The ribbon tab contains a dynamic menu which has a list of buttons generated at run-time. I would like to add new line to the button's label and/or description but not sure how. I tried adding newline character ("\n") to the button's label and description but it looks like the newline character is ignored.

Thank you.
