Can we setup an popup message based on action reason selection in Assignment page.

Requirement:

We have an requirement to enable auto popup message on screen when ever an particular action reason is selected by manger.

Example:

If Manager selects Action as "Resignation" and Action Reason as "Exit of Intern" and auto popup message should be displayed on screen showing that "This reason code should be used only for Interns".

Is it feasible to configure.
