Associate a specific list with a table of unique records

I am creating a C# application that will log a product request.  That request will require 10 approvals.  I want to maintain that list of approvals in its own table so they can be added, changed or removed and not affect the product request records . What I want to happen is that when a new product request is created a set of associated approvals are created in its own table.

 

Is this the best way to handle this?  I need a little help putting this together.  Thanks
