Reusing n.s.photos?

Hi,

I got two sites within one SG. I got a topic trees like that:

site-one-root
{
    galleries
    {
        gallery1
        {
            photos
        }
        gallery2
        {
            photos
        }
    }
}


site-two-root
{
    galleries
    {
        gallery1
        {
            photos
        }
        gallery3
        {
            photos
        }
    }
}


As you can see gallery1 should be shared between two sites. I don't want =
to make copies to avoid multiplying files and using too much of a disk =
space. Is it possible to somehow symlink n.s.photos topics?
