How to gradient transform for every frame

Hey i have a keyframed shape drawn animation and i want to add a gradient to a body part. Ive chnage the angle and size of the gradient but want to have it in the same direction for each from, i know theres a way to do it becuase i accidenlty did it where if i would select another frame and press x twice to change the colour and then change it back it would keep the gradient transformation however i cant do it again

any helps appricated thanks
