Waviness Direction

Hi
I creating presets with Waviness effect and i notice i don't have an option to change the direction of the animation from the node itself.
for example - if i choose horizontal, the waves can only go from bottom to top but not the other way around.
is there a way to do it?
i have tried to use a transform node and click on flip but it will effect the entire comp while i want it to effect only on the waviness effect.
