Auto Populating Drop Down List

edited 12/09/19 in Smartsheet Basics

New to SmartSheet, and want to use it to keep track of tasks. So, I created a "Project" column in my task list, and set it to a drop down, not limiting the entries to values in the list.

What I am looking for is, that when I create a new task,  and type a value to the Project column that doesn't exist on the list, that it's automatically added, so that for future tasks, I have an active list of projects, without having to go in and edit the column properties every time a new project is adde.
