How to add fit call outs with precision

I'm trying to detail metric drawings for a hub and shaft set that use a keyway.  I want to call out the fit (normal/close/free) AND the associated precision.  It should look something like this:  2N9 (-0.004/-0.0029).  If I add the "N9" after the in the Dimension Text, it places it after the bilateral precision (so 2 (-0.004/-0.0029)N9).  Alternatively, I can replace the with 2N9 but then I can't have the bilateral precsion.  Is there a way to work around this?

Thanks,

Steve
