GCOR 6.4
Answer: Yes, per GCOR 6.4
Feedback:Controlled sidings require either verbal authority or a controlled signal displaying a Proceed indication to enter. Unless Track and Time was granted in the controlled siding, the authority is in one direction, which means it is possible to move opposite the authorized direction. Since the train crew is making this move within the same signaled block, no permission from the control operator is required. If the train crew were to go outside of their same signaled block, permission from the control operator would be necessary.
