Currently, when we select and determine a record on the Lookup field, the record name of that entity's primary field is displayed.

However, we do not always want to display the record name of the primary field in our operation.

Sometimes we want the Lookup field to display the record names of other fields that are not the primary field.

We think that if we can select the target field that will be the record name to be displayed on the Lookup field,Dynamics 365 will be more convenient.
