Symbol Tutorial

Good Day All

Another question re weld symbols.

I am trying to create a weld symbol for a joint containing a bevel and a fillet. I found the COMBINE weld symbol in the library and this looks (to me!) as though I can create a symbol for my requirements. Unfortunately it does not, I can only choose one weld symbol per side whereas I need a bevel and fillet symbol combined.

I have trawled the forum and online training and cannot find a good tutorial on symbol editing. can anyone point me in the right direction or help?

Many Thanks
