Copy Extended associations

When copying a motion sensor with Copy Extended the generated Group Addresses are associated on channel level instead of device level. It would be nice if we could change this.
Example current situation:
Sens1 output1 0/0/1
Sens2 output1 0/0/2
Sens1 output 2 0/0/3
Sens2 output2 0/0/4

Preferred:
Sens1 output1 0/0/1
Sens1 output2 0/0/2
Sens2 output1 0/0/3
Sens2 output2 0/0/4
