Look Direction of a gameobject

Hey there!
I have a gameobject and when i click on this object, it looks in the direction of the camera (with the function lookAt() ). Is there a way to save the ‘old’ direction, so when I click on the gameobject again, it looks in the old direction again?
Thanks for your reply!

Sure just store the transform.rotation in a Quaternion variable and set it back on the second click
