Electrical symbol wiring

[Richie_Rich]

I'm sure this is an easy answer for most of you (or at least I hope so anyway). Is there a way to either create or make an existing symbol attachable with the electrical connection command? There are times I use a symbol in the chief library (that is an electrical symbol) that won't make a connection with this command. I'm guessing I just need to check a box somewhere?

 

Thanks in Advance for your time!
