I have use case that
I create custom data with ini file for input data by user for new device by get value from message box example device_group and user input “north”
and I have import custom attribute for existing device example device_group “north” , “south”
so, finally I want to update between custom_data and custom_attribute
Copy %customAttr:device_group% to %CustomData:device_group%
and
Copy %CustomData:device_group% to %customAttr:device_group%
