Make default primary required field into a lookup

Question

When creating a new entity, a new form is automatically created for you where it automatically is given 2 fields, name and owner. For the name field, it is possible to make that into a lookup?

Answer 1

No, the primary field can only be of the type Single Line of Text.

When creating a new entity, you cannot select other types:

This does not stop you from changing the requirement level of the primary field to None and creating your lookup field.
