Hide from Lync Address Book

The ability to hide Lync or non-Lync objects from the Address book. I know you can use msExchangeHideFromAddressBook=TRUE and I wouldn't like to lose that function, but there times where CEO's and others, want to be hidden from the Lync phone list, but not hidden in Exchange.

Perhaps a 3 choice option: Null (or 0) defaults to the Exchange attribute setting, 1 ignores Exchange and Hides, and 0 (or 2) ignores Exchange and makes visible.

Also the ability to Filter the results to specific OU's, or exclude OU's.
