Hi Thanks for your support. As it is connected to both Firmware of the controller Program and APP Program, which includes all the UI Design, Android version and IOS Version APP Programming. It is quite a lot of work actually. Therefore we have to be very careful in adding functions. We will report your feedback, and spend some time doing market interview. And if it is a common demand from market feedback, then we could arrange schedule for adding this new function. Thanks for your understanding.Is this something that is expected to be added? Seems like a no brainer.
