Collecting more than one employee record in a form - Master Detail

Hi, 

I am new to MS forms and thank you in advance for your help. I have to develop a form where a supervisor fill in his information (name, id, email) and then fill in more than one employees information (name, type, id, details of request) in the same form like a grid. Then I want to save the supervisor information and the employee information in separate records in a SharePoint list. The supervisor information will repeat in each row where are as the employee information will be unique for each record. Any idea how to accomplish this in forms? Basically my manager don't want the supervisor to fill in his information multiple times.

Please let me know if you have any questions.
