I have a few parts with custom holes using the hole wizard. When ever I edit the profile or locations, the sketch for the profile is recreated, and the number of the sketch is incremented. For example, if the sketch that contains the profile is named "Sketch2" and i edit something, it will be recreated and labelled "Sketch3".  If change anything again, it will become "Sketch4", and so on.  This is problem because I can't have anything reference these because that link will become broken if i change anything. 

Whats going on here?
