Autoresponder is a great feature, but it works only with response.
I and my coleagues have a many cases when need to replace request headers, params or body

breakpoints isn't good, coze sometimes application dont wait and drops connection to requests

Examples 
mobile request is post only with curent time in body, but i need to post this request with past time.
Backend is accept body with past requests
I dont have access to DB to change time, and no requests to change time. Also app is works only with current request (i can't use composer to create another request)
