Is it possible to geotag images via the pentax image sync app?

ideally coordinates would be sent via BT4 to the camera that writes them into the exif data.
should drain less energy than sending image to smartphone (but then any number of apps could be used, but often use average coordinates via time stamps so quite often wildly off chart ...).

are there any third party apps that can be used with pentax kameras to do what I just described?
ie. at the time of exposure send gps coordinates from smartphone via in-phone app via BT4 to camera that writes in the exif data.
