Square butt weld of pipes

I have couple of hundred pipes in an assembly that should be welded together using square butt weld. There seems to be a way of adding a "pattern", but this doesn't seem to exist in Creo 4. I can't find the option.

Further more, all welds are of the same type, so all I want to show is the weld number. How do I remove all the other parameters that are shown?
