Are you talking about the cosmetic thread that is the dashed lines, or the cosmetic thread texture?
The dashed lines automatically pattern with the hole on my machine (SP4 EV). Maybe it is a problem with SP1?
If it is the texture, that is a known issue.
BTW, I really prefer to have all holes which serve the same function to be in a pattern instead of multiple points in the Hole Wizard. It makes using derived patterns in the ass'y much easier.
