Reuse Animation directions

Hey,

is there a way to reuse my animations in terms of general direction put not hard point? I got a slide to the left, which i want to use for my other objects as well. Going there is no problem, but coming back, every object goes to the same point, because, of course, the animation has a hard endpoint? Is there a way to use the animation as a sense of:

position = position + x;

position = x;
