Maintaining Single-Table Inheritance in EOModeller?

Howdy All,

I am doing something with single-table inheritance in EOF using 
EOModeller.

I have an entity A corresponding to a base class A mapping to table TA.

I have several entities B, C, ... corresponding to subclasses of A 
mapping to the same table TA.

A has a lot of attributes and relationships.

I have set this up using the Property > Create Subclass menu item.

My problem is that every time I make changes to entity A it seems I 
have to either manually edit the entities B, C, ... or delete them and 
recreate them as subclasses.

This is a maintenance nightmare (for me at least).

Is this true or am I missing something?  I thought at least the changes 
in entity A would automatically show up in B, C, ... but it seems 
subclassing in EOModeller just does a one-time copy.

Another reason for a new version of EOModeller?

Cheers,
Ashley.
