Autofill Requester Details on all New Requests

Autofill Requester Details on all New Requests

On all new Requests, we would like the system to autofill the requester details with the details  logged in user. 

This is working well on Incidents but new Requests requires us to select the Requester. 

Any solution to turn off the requester and let the system use the login user as requster. Currently the requester details also cannot be deleted
