How to get/set id for pm.sendRequest before executed?

I want to execute multiple pm.sendRequest and record their id, so that I can map the responses.
Where I can get or set the response id after executed pm.sendRequest?

The sendRequest method has options for error handing and the response.

In the following example, the response is being saved within the variable “res”.

Which is then parsed as you would normally do.

      url: ',
      method: 'GET',
   }, function (err, res) {
      if (err) {
      } else {

          pm.test("Status code is 200", () => {
          let response = res.json();
