Title Field of Child DocType

To make a long story short, I have a Doctype that references records from a child Doctype, but when it loads, it shows the system-generated name of the record (created by Frappe). Is it possible to display a different field instead of the default name or title field? For context, I can’t use that field as the title because its value may be the same across multiple records.

Try using this?
