fractions for hole callouts in hole table?

Is it possible to somehow get hole callouts to display as fractions in hole tables?  I figured out how to get drilled holes to display as fractions by using but this doesn't work for counterbore hole sizes or any holes created by doing an extrude-cut.  Tech support said it can't be done but I have already partially proven this wrong by using .  I am using SW2008.  Do newer versions have this capability?  Thanks!
