Update all text boxes with new version of font?

If I install an updated version of a font, I have to do the following to update all the text to reflect the newest version of the font:

1. Reload the tab for the file in question.
2. Double-click each and every text box that uses the font.

Is there a workaround to having to do Step 2? Perhaps an as-is regex find-and-replace (style-based)?

Or better yet, would it be simple to write a script or extension that goes through every text box in a file and updates it? Does such an extensions already exist?

Thanks in advance.
