DAST repeat / tamper with http request

[domwhewell-sage]

I don't know if this idea has already been brought up or there is a way todo this but I was thinking of a new section for repeating the input request and tampering with it before it is sent.

For example

tamper:
  - part: header
    type: drop
    name: Cookie

This would be part of the http protocol in the same way fuzzing is but the objective would be to repeat the http request and in this example remove the cookie header for Broken Access Control testing.

Or you could have a

tamper:
  - part: header
    type: replace
    name: Cookie
    value: connect.sid=blah

Which would replace the connect.sid cookie with another users
