Basically I need to add a new nested relation to an schema, that I already use in other services, without this implying a change to the rest of the functionalities that use it. Since I work with sqlalchemy, if I include the new relation, new unwanted statements appear everywhere, since the ORM tries to fill it. I would need something like adding the relation, and specifying that be only included if I specify it. Any ideas?
Note: Create a new schema is not a good solution since the affected schema is deep in the relation, so I would have to create all it's fathers too.
