Modifying SW Built in Weld Symbol Creator

So, is there anyway to modify the Solidworks built in WeldSymbol creator? We have an older weld symbol standard that we stilluse on our drawings and would like to support it in the automaticcreation of our weld symbols. Problem is, SW calls it outdifferently, and not to the AWS standard we use.

Anyone have any tips on how to do this?

Thanks in Advance.SolidworksApi macros
