Allow only some users to share externally
Controls exist to limit sharing to Internal, Existing External members, New and Existing External Members, or Anyone with link. A separate control exists to limit sharing to specific external email domains. Add an option to only allow some users to share externally. For the most part, our users shouldn't be sharing, but there are always exceptions (executives, marketing, legal, etc.) that will share with an external party, but no way exists currently to allow them to share externally without allowing everyone.
Hope can help this enhancement in the near future
