Questions Deleting Details with Postman

Hi All,
I'm trying to delete all sales people from a customer using Postman. I know this could more easily be done with an import scenario, but I would like to better understand the API and this seemed like a good test.

I'm running a PUT to the following address. It deletes a single salesperson from the details (not all of the salespeople). Is there a way to modify this to delete all of the sales people for that customer? 
Thanks!
