You should be able to add offset to the second half of a copy to command:
Ex:
Group 1 Copy To Group 1 Offset Reverse
Group 1 Offset Mirror Out Copy To Group 1 Offset Mirror In
Chan 1 Thru 9 Copy To Chan 1 Thru 9 Offset Reverse
Currently the offset key does not post after adding "Copy To" to the command line.
