Re-tether feature for Sony Cameras

I do corporate headshots and need to move from my tether cable to do a group shot and shots with CEO, directors and other heads of staff. This feature I know was greatly welcomed on the Canon and Nikon side as it would be on the Sony side. It would be great to not have to search for the pics done outside of the tether cable and speeds up delivery time to the client and being able to jump right into editing after the shoot as some my want a photo at the end of session just to show others for meetings before full delivery.
