Hello!
How to make an object rise in y for some distance cyclically, regardless of where it was originally.
Those. I have a square that moves from bottom to top in the center of the screen. I copy it to the bottom left corner of the screen and it also moves exactly from bottom to top.

Damn, I found this solution. Free Motion Tools script (similar to Motion - Mt. Mograph).
You select a layer, in the script window you press add null, move it where necessary, delete the null layer. Profit
