control multiple positions with expression
HI everyone, I am trying to simplify something I’ve dealt with before, and because there is a logic to it, it must be something an expression can accomplish.
See below for a link to a very simple ae project.

( Position 1 is off screen and position 4 is off screen )
In the example ( the white box ), in order to change the 2nd position, a user would need to select the exact 2 keyframes where the position is the same and move the position. They would have to repeat this process for the 3rd position by selecting 2 different keyframes and then moving those as well.
I think this part alone can be solved with an expression with no keyframes at all, ( see the yellow solid ), but I only managed to figure out the first move, from the 11th keyframe to the 27th. After that, I only had errors when I tried to add to that expression.
(see below)Also, the key frames from the white box are in easy ease in and easy ease out with the velocity adjusted to 90.
This creates the look that the artistic director desires.So I was hoping that there was a way for the math.exp function to be included into the expression to help recreate that Bezier curve between all keyframes.
So, in summary, is it possible to have an expression control multiple position keyframes from sliders, and secondly, is there a way to cheat the animation with the use of a math function to mimic the Bezier curve ?
Thanks everyone
