I have done this on other engines. My method in this case is to turn the engine backwards past the TDC point a few degrees using both the crank and the camshaft (to keep tension on the forward side of the chain), then come back forward to my setpoint.

I would be concerned about arriving at a setpoint going backward as you described because of possible errors due to slack in the chain or timing devices etc.
