back drill for ej pins

hi all,

Just wanted some input on how to show the back drill for ejector pins. My technique is to use the hole wizard to add the ej pins. Then I would use the hole wizard again to show the back drill. The problem is the hole wizard doesn't recognize the ej retainer plate. It is selected in the feature scope & the preview shows correct, but the hole don't appear in the model. The technique I used in the past was to edit the sketch for the side view of the ej pins to add the back drill. The problem with this is if you go back & edit anything in the feature tree above this, that sketch will blow up.
