Clone a FreeNAS jail

I am looking to make a working clone of a jail.
I have a minidlna jail running on my lan segment. What I would like to do is have another minidlna running on vlan20 also.
I know that I could make a new jail and then configure it just like the first minidlna jail, but I would rather just make a working copy of the jail, and then change the vlan in freenas.
Is there a way to effectively clone one freenas jail to make a second instance of the jail?
