Feature request for a Glide mode as a flight mode

Hi all,

I couldn’t find any mode in which I can Glide back to my launch position from high altitude without using any motor power where plane maintains direction and min airspeed by bleeding altitude enough not to stall or maintain certain set airspeed.

This mode can be beneficial when you ant to save battery while gliding back to home without any anxiety of monitoring the airspeed all the time.

If there is already a way to accomplish this ,then please let me know. Thanks in advance.
