iTween change orienttopath mid path?

I did some searching around for this and wasn't able to find anything. I'm looking to have my camera orientate and move along a nice, complex tween path and after a certain percentage of that path abandon the orientate to path functionality and start looking at a look target. Is this possible? I assume that because the orientatetopath variable is set at the start of the moveto call that I can not change it mid path. Is there some other option? Am I able to move the camera along the path and have an iTween.rotateto function orientate to the path and after a certain time stop this rotating and then have a look at applied? Anyone else ever do anything like this with any success? Any help is appreciated.
