_USTN_PROJECTDESCR in Title Bar

I am looking for an vba to place info in the title bar.  It would be nice if there was a variable that you could set that it would read the _USTN_PROJECTDESCR variable and place the info in the title bar.  I have several projects that are similar and some people are getting confused with what project they are working in.  So I would like to be able to place the project description in the title bar.  Is there anyway to do this?
