Is there a way to make bulleted numbered list?

What I need specifically is to create a list like this

§1
1. xx
a) yy

§2
1. xx
a) yy

and later add references to specific points and subpoints in the form of "§1 1. a)".
The fields would update when the structure changes.
Right now these references look like this "§ 1. a)".

How do I make the paragraphs act both as bullets and as a list? Or maybe tere's a way around it?

Thanks
