One-Way Relationship

Is it possible to establish a "one-way" relationship? Example: My first app is a "coreAPP" which contains many standard object. An example is the object "Countries". I then create the following apps: secondAPP: Core Object: "Person" Dependent Object: "Countries" Object "Person" has a many-to-one relationship to the object "Countries". third APP: Core Object: "Car" Dependent Object: "Countries" Object "Person" has a many-to-one relationship to the object "Countries". When I then try to install "FirstCoreApp" and "thirdAPP" on a customerzone, i get an error that it is missing the object "Person". This is because there is a relationship (reverse) from the "Countries" to "Person", which was established in "secondAPP". Is it possible to remove the reverse relationship and still get this to work? If not, what is recommended: * Add most object as core object in a coreApp, and dependentobject in the other applications? * Adding the same object as the core object in many applications?
