Attach a socket to another socket

There is something specific i want to learn. Can i attach one socket to another?

I know we can attach an actor to another actor’ socket. But thats not what i want. In my specific case, i have a bow. That bow is already attached to left hand socket. I want to know if i can attach bow’ string to right hand socket at the same time.

Thanks in advance

NOTE: This is just something out of curiosity, not because i need it.
