There are solutions for A-B paths, A-B-C paths sequence
The problem with those is that once once you change path you jump from position to position since position B from path 1, and position A from path 2 are not animated.
So what I am looking for is to have a list of positions 1,2,3,4,....N, and when I click one of the buttons to move the camera from the current point to that point.
How much time for that transition? Simply have a field for that and take that active value as a transition time.
Is there something like that?
P.S How does the camera mover module work? (in case I have to build the previous functionality by myself.
Just set the same position for A and B and enable Smoothing in in the Camera module. You can adjust smoothing for each path to control how fast the camera moves.
