It's a Distribution List, which some email programs simply call a "group".
Since the Directory uses your email program to send emails, it's a simple matter to copy any set of addresses that is generated when you use the Directory's send email feature. With most email programs, you can then save that list of addresses in a group or distribution list.
Of course, such a distribution list is static -- it won't change as people change callings or organizations, but it would provide the basic functionality desired.
Questions that can benefit the larger community should be asked in a public forum, not a private message.
