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.

Did you try to create your wave effect outside of your main flow and merging it where you want it?

You can DM me the script if you need further help.
