Report # of descendants / find candidate MRCAs?

Hello, I’m wondering if there is a way to use Rootsmagic to identify potential MRCAs for living people? For example, to create a list of people ordered by the number of descendants that they have? Or for each living person, to list the cousins that they have?

Just curious, how are you planning on using that information? Isn’t every descendant of my gr-gr-gr-grandfather a cousin, of some sort, to every other of his descendants, besides parent-child pairs?

And sorting people by the number of their descendants will tell you more about the depth of your research in different family lines than anything else. A relatively infertile family line could have 20 descendants strung out over 10 generations, while a more fertile line could have 20 descendants in 2 generations.
