GPS function in variable (Automatic GPS capture)

I there any GPS function I could use in a variable to get the interviewer’s position. Trying to avoid having him/her press on a button in GPS question.

Use a GPS location question to capture the device location at that point of the interview. If you need it for anything else, please explain.

Thanks for the response.
The aim was to grab the GPS coordinates in the background, without Interviewer being aware of it. Is that something Survey Solutions can do?
