Triggered Requests in Gatling


I am fairly new to Gatling. Its been a good learning and the documentation has been good so far.
I have a question on some requests that are triggered after my post request is triggered.

So this is what I am trying to do , I post a request and there after there are some functions that run on the back end and trigger 2 more requests. Is there a way to test the performance time for all the three requests took to complete.?
