Please add "Auto IP Renew" option when AP is changed in CPE mode

Hi, I’m using mAP in CPE mode in my car.
This little box is connecting to known WiFI APs and sharing the Internet with main LTE router over the Ethernet.
All needed WiFi networks are added to Connect list and nicely switching when I moving from one area to another.
There’s only one caveat: for some reason WAN DHCP IP not getting released and renewed when mAP connecting to other WiFi AP.
Surprisingly I found no options to set it up and had to write simple script which monitoring WiFi AP change and release and renew IP after that.

It would be great to add an option which enables DHCP IP renewal upon WiFi AP change in CPE mode.
Thanks!
