Provide a way to hide/exclude option for "All recipient types" in Dynamic Distribution Group applet
Provide a way to hide/exclude option for "all recipient types" in Dynamic Distribution Group applet. If an admin accidentally forgets to change the default selection (All recipient types) in a new DDL/DDG, an email sent to the resulting group will go to most mail enabled targets to include contacts and other external users. We would like to be able not allow the selection of "All recipient types" in our tenant to reduce the likelihood of unplanned broadcast emails.
If hiding the option isn't an option, at least the "All recipient types" choice should NOT be the default selection. Even though the current structure of the new ddl is by design, it is a poor design that doesn't consider the risk of such a selection.

Another option would be a pop up that would ask you to confirm that you want to send to "All Recipient Types". This way you can decide if you do or if you want to cancel.
