Explanation
To identify new leads entered by interns from existing leads, the administrator should define a record type and assign it to the interns. This will allow them to select a different record type when creating leads, and distinguish them from other leads based on record type. Setting up Web-to-Lead form will not work if the interns are entering leads manually in Salesforce. Creating a separate Lead Lightning App or updating the active Lead Assignment Rules will not affect lead identification. References:
