facetime, in the top middle instead of just right and left side of screen

Can Apple add to Facetime that you can drag your insert picture to the middle top of your iMac, just under the camera? Right now, with the large iMac screens, if you look at your insert to see if you're framed, etc., you're look off. But if you can drag it to the middle under the camera, then it looks like you're looking in the camera. Apple never thought of doing this when the screens/monitors were so small. Right now you can't drag your insert to the middle, it just slides to the left or right.
