Hi Tyco,
Welcome to this Microsoft Project newsgroup
You can! Just select the ID number for the task and Format/Font - give it
whatever highlight you want. You can automate this by recording a macro
which you can put on a toolbar for instant use and a second one to remove
it. If you want details on how to do this, you might like to have a look at
my free series on Microsoft Project in the TechTrax ezine, particularly #16
on macros, at this site:

Thanks.)
