Can we upload a polygon and expect the GPS recorded is within the polygon?

How can we make sure that interviewer recorded the GPS in the certain area we sent them. I have tried the lookup table idea that includes uploading the extent of a polygon but it will accept the GPS within the extent.

like in this image there is a polygon of a district and square box came after plotting the extent of that district. Now the problem with uploading the extent in lookup table is that, it will accept the GPS recorded with the square. but we would want interviewer to record GPS within the polygon.

Hope I have made my issue easy to understand
