Slot length parameterization

Can I assign a parameter to the slot length in the Hole Wizard?  I tried putting dimension reference in the Hole Wizard window (e.g. D6@Sketch3, and =''D6@Sketch3'').   And I tried to Configure the Hole Wizard feature (can only un/suppress)...  I could just ExtrudeCut the slot, but not sure if SW has a secret way.

Thanks,

Jesse
