Is it possible that for our PointSolutions Instance, that the Region be locked to North/South America since this is the only region students are expected to choose for our instance of PointSolutions?

Every beginning semester we are finding that a minority of students (even with instructions provided) are choosing other regions besides North/South America and are then missing out on in class polling opportunities.

While discussing this with support we were discussing how to implement this and we were wondering if maybe we could prevent SGU users / emails from logging in to the other regions.
