Hi, Martin.
Thank you for reaching out!
Can you expand on what you're trying to achieve, or possibly share a .story file with your ideas?
If I understand your request correctly, then it's something that you can already do in Storyline. Take a look at the example below:
The object moves through a Line Motion Path (with relative starting point) every time the user presses the left arrow key:
There is a second Line Motion Path that starts and end at the same position, which is activated by the Clear button:
Regardless of where the object is, it will move it back to the original position when the button is pressed.
Is this similar to what you're looking to do?
