[Plugin: NextGEN Gallery] Multiple settings

I am developing a site for an artist friend, who needs it in several languages. The most convenient way of doing this is to have three separate subdomains, one in each language. However, having an extra three sets of galleries means that the site will quadruple in size. Is there any way of importing into a post a gallery from the root site? That is, for example, in the sub-site catalan, import the gallery and its settings from the root site?

I am not sure this is completely clear! It is rather difficult to explain!

Thanks
