Excel 2007 : Add icons for Quick Access Toolbar

Hi

I have added a couple of macros to the quick access toolbar. However, none of the extra icons they provide are close to describing what these new buttons do. Is there a way to add more icons? There must be a directory where excel stores these, and where one could add an extra image file in to have it appear when you click "Modify".

Thanks

As with so many things in 2007 where you think "there must be...", there isn't. For the only good way I know of, see Ron's page here.
