Hovertext on dropdown

[NGilbert]

In short, what I am trying to do is have a drop down with numerical values, but when you hover over a value it will give you a hovertext or mouse over (whatever you call it) with more information.

Example:
An evaluation with a dropdown that would rate a product 1-5. When you hover over 1 it would say "Poor", hover over 5 it would say "Excellent".

I hope someone understands what I'm getting at and is this in any way possible?

Using a Word content control you can give instructions like "Choose 1 (poor) to 5 (excellent)" as the title in the properties of the content control. When someone clicks on Choose, the title pops up above (but does not print).
