Ground Green Wire Nuts

I asked a question last week regarding crimps for the ground and it was suggested I should use Green Wire Nuts which would be code for tying the ground wires together. I understand you put one ground wire through the hole in the wire nut but what if you need two for example when you have two switches requiring a ground wire to each in the box. Do you just use another 6" jumper secured by the nut so you would have one coming out of the hole in the wire nut and one jumper tied to the other wires secured by the wire nut. Does the one that comes out of the whole in the wire nut have to be 12" as you would have 6" normal in the box then threaded through the whole in the wire nut (asking if it has to be 6" long from the whole in the wire nut.

 

tie a eight inch wire with the main wire under the wire nut, have 4 inches out the top and four inches out the bottom. or get the bigger green nut and have two wires and the main out the bottom and one out the top
