Possibility to add a status message (alert box) after screen submission in FormBuilder

Overview

I would like to be able to send a status message (for example: Activity saved etc.) once a form that I have created with the FormBuilder is submitted.

Current behaviour

At the moment I have created a form with FormBuilder which I use to add data, for example an activity. Right now once I have entered data and hit the "submit" button I am returned to whatever page I have entered at the Post Submit Page, but I do not get confirmation that my data has been saved.

Proposed behaviour

I would like to be able to specify that I want a status message when I have created, updated or deleted data.
