Unfortunately, your assumption that you can only add another branchgroup is
correct, given that you have a compiled or live branchgroup.
You CAN create the transformGroup on the fly, but in order to add it to the
live branchGroup you must 1) create another (new) branch group, 2) add your
transformGroup to your new branchGroup, 3) add your new branchGroup to the
live/compiled branchGroup.
