There are several ways to achieve this:

Lets say you have two entities (A) and (B) both contain an attribute called name.

- Have a third entity (C) that has an 1-1 associations to A and B, create an instance of C for each instance of A with the association to A set, create an instance of C for each instance of B with the association to B set. List this entity (C) and show the data via the associations (you can add conditional visibility based on the condition if the association is not empty)

- Have a non persistent entity (D) with attribute name, create an instance of (D) for each instance of A and for each instance B. Copy the value name to the attribute name on the NPE and list this NPE entity

- Have a specialization entity with the attribute name and let A and B inherit from this entity

It really depends on the use case, the amount of changes, where it is displayed which option makes more sense
