Experts of Isogen :Is the above possible ?

I used to think you could not redefine endtype symbols. Guess what, you can. I changed the threaded (SC) endtype just this morning from a horizontal U shape to just a line.

Now I need to remove the weld dot from the SW fittings. Now this is the issue. It appears this is a combination of two SKEYS being SW + something like WW.

I am really not keen on redefining all the valves and fittings and bedsides you cannot redefine Tees and elbows.

Help me.
