Option to change the Record label for display

Scope & Context

Display field of a record

Current behavior

In people, the record label is set to name, and can't be edited?

<img width="744" height="302" alt="Image" src=" />

Expected behavior

Give option to choose any field (even later calculated field) to be set as record label for display. This is needed because simple combination of firstName + lastName can be in dozens, so unable to easily distinguish among the people just by seeing the record label or while choosing the person in some associated object.

Better to let business decide which should be the display record label: either
• the combination of fields, e.g., firstName + middleName + lastName + nameSuffix.
• or, a single field, because anyway calculated fields are on the way, right?
