Hide IVRs from Dial by name Directory Merged

Currently when you type the name of one of our properties into the dial by name directory you see all of the IVRs for that property (example, for our property Northway we have an IVR for Northway After Hours, Northway Spanish Mailbox, Northway Main IVR, etc, and all of those show up when you type in Northway). It is not clear to our internal employees which to choose if they need to call the property. We would like the ability to flag an IVR as to whether it should show up in the dial by name directory or not.
