Removal of the Default Change Activity

So we figured out how to remove the Default Change Activity because we create our own from various types and create the Change Name. In 9.1 we had this removed, and if we started the change notice from the object, it would still populate in our new change task on the affected objects.  Where do I edit to get the object to populate on the affected objects table in 11.0 after removing the default change task?

Also I noticed the order of the Change Task subject is displayed different.  We prefer the Change Name, Type, Number rather than Type, Number, and Name in the subject.  Is there a preference setting to switch this back?

Thanks.
