after effects jsx reset position

I need a quick way to reset the position of a selected layer to 0,0.
I found this jsx script:
https://github.com/kyletmartinez/After-Effects-Scripts/blob/bb0c5f7ce7584457fc8c58bb070c37e15f86918d/scripts/Zero%20Position.jsx

which zero’s the position but creates a null to do so.

*I just want to change the x and y values back to 0 like a reset position function*

(Its for a character rig / head rotation layer that I constantly need to reset to 0 so i can make changes to the default position of the head and then move the x y coordinates to see if the change was successful.)
I can then add this .jsx file to a kbar icon and then it would be super fast fixing my character rigs in the future.

thank you and it would save me so much time if someone had a solution. not much of a coder but can copy paste and understand with trial and error.
