After mentioning the requirements in SAS Management Console to create and edit Shared Prompts (https://blogs.sas.com/content/bi/2009/09/24/creating-a-shared-prompt-for-multiple-imaps-and-stps-9-2/), I then came across functionality in SAS Enterprise Guide 4.2.
In the 'Server List', there is a small blue circle with a 1-2-3 and when you mouse over you will see 'Prompt Manager'.
All of the prompts change the subsequent selections on the screen.
My favorite (date range) allows a wide range of options for the user (see below):
The next 'slick' item is that there is a 'Used By' column in the Prompt Manager screen. Providing the prompt manager a quick take on how the prompt is being used, as changes could negatively affect reports that are using it.
