You don't have to have a physical hole feature in the model, any circle in the draft view is valid for a hole table.
So, in your draft view go to Draw-in-View and place circles at the points you want. You could also place point elements, at a different colour and thickness to make the point more visible in the drawing.
Exit draw-in-view.
Create your hole table to these circles.
Now go back to draw-in-view and change the layer of the circles to Auto-Hide.
When you close draw-in-view the hole table will still be valid but the circles will not show.
