MU and Edsva attributes

Dear Reader,

I've tried to create a Managed Unit for the attributes edsva-MsExch-ProtocolSettings-ActiveSync-Enable and
edsva-MsExch-ProtocolSettings-UpToDateNotifications-Enable. These are for the ActiveSync and Up To Date Notifications settings in the user's mailbox features.

But it seems that i cannot find these attributes through the Managed Unit or query them through LDAP.

I had a chat session with support and he also found that he couldn't find or query the virtual attributes in MU's for AR 6.7 or 6.8.

So is this something that cannot be done for MU's in AR? If not, would be a cool feature for 6.9
