Composing MAReport

Is it possible to compose an MAReport to use fields from different  
objects?

For example, the person editor exercise has a PersonModel that  
contains an AddressModel.  Right now, an MAReport on the PersonModel  
shows the AddressModel instance as one column.  Would it be possible  
to show only the Country field of the AddressModel (and have the  
columns titled 'Country', not 'Home Address') in the report?

Thanks,
David

Yes. You can add columns manually using #addColumnDescription:. Just
make sure that you change the accessor object, so that it reaches the
other object. For example:

aReport addColumnDescription: (MAAddressModel descriptionStreet
     accessor: #(address street);     " calls #address on the
receiver, and on the result #street "
     yourself)

You can also directly add such a description to the PersonModel if you
need it everywhere.
