Can we set up a rule or have another method to auto relocate the devices to their original group when the billing period starts again ?

In our case, we want to monitor the monthly cellular data usage on our Android devices.

I have created two groups : Group A - original and Group B - data usage exceeded :

- Required action 1 :  relocate the devices which reached the limitations to the Goupr B - Worked by TEM feature !

  I have set up a telecom expense management rule that works well.

- Required action 2 :  auto move the devices back to Group A - original when the billing period starts again - Did not find the feature in MobiControl

 I saw that the device relocation rule can automatically move devices between groups, but It is based on changes in the IP addresses or other specified custom data. 

The issue of the two options for us is : 

option 1 : changes in the IP addresses

We do not know which devices will relocate to the Group B. We need manually add the IP addresses and change the activation schedule at the end each month.

option 2 : specified custom data - .INI File / .XML File for Android+ devices. Do you have any idea which custom date is available for our case ? 

Thanks,
