I would be nice if we could configure the Intelligent Types functionality.
So for example we could supply a regex and when that regex is matched when adding an Attribute to an Entity it would default to the indicated type.
The business use case for this is where we have terminology used within the business that should always have a given type. So rather than having to manually select the type it would default to the correct type.
PS: This suggestion has been contributed by my collegue Matt Foster (so he gets the credit!)
