Group centrality measures

Forgive me if this has been discussed before (but I couldn't find in my search): is there a group centrality measure in NodeXL? That is, is there a metric which measures the degree with which a group (e.g., NGO) is nearer to all other groups (e.g., government, corporations, bankers) in a network either directly or indirectly? For individuals in a network, closeness centrality will be one such measures.

While waiting for someone to respond to my question, I came across that Everett and Borghatti (2005) did provide group centrality measure [Everett, M. G., & Borgatti, S. P. (2005). Extending centrality. In P. J. Carrington, J. Scott & S. Wasserman (Eds.), Models and methods in social network analysis (pp. 57-76). New York: Cambridge University Press.]. I, however, have no idea how to implement that in NodeXL or if it is even possible to implement such an extension. So, I hope someone in the NodeXL core group is reading this mssg and will respond. I really could use the help!

Thank you for your help - appreciate it.
