Unless you’re using a 3rd party plugin. If you have one track point, you can’t attach it to another and apply them together for rotation and scale. In the tracker window, there is an option to track rotation and scale, which will use two track points that are attached to each other which will apply position, rotation, and scale to your target when done.
At leas that is my understanding, maybe someone else knows better. As far as 3rd party plugins, I know they exist, but I don’t know any because I’ve never had to actually use them myself.
