Can you require a geopoint to be updated?

[TL2]

I am preloading locations in my Inbox and would like the user to update the location for better accuracy.  Right now, I have added an accuracy field and am capturing that - making that field required/read only so they must retake the point.  Is there a way to force the user to update a question without adding this second field.

As I run off to a meeting, here is my simple answer...

Add this to your survey:

Then make a calculate that uses this as input, and require that this equals... something. I forget offhand what the numbers mean, but just collect a geopoint once and you will have your answer. There is your requirement. (more info here)
