DP Multisite: saving theme/plugin configuration (cloning site)

Hi, I’m using DP on a multisite setup. I want to clone my original setup under a different subdomain, so, my questions are:

a) is it possible to save the theme/plugin configuration (eg, including packages, memberships, etc), so that I can import them back when the new site (subdomain) site has been setup?

b) is it possible to clone a sub site?

thanks a lot and a great 2014 for you all!
