k95 rgb (Request Help) Ripple Pattern From Arrow Down Key

Welp, I've looked everywhere and couldn't find a thing. I tried to figure it out and I guess I'm too Dain Bramaged for this.

What I wanted to do was a permanent Ripple pattern that starts from the Down Arrow and spreads out from there. If you want to visualize what I mean. Take a blank template, add Type Lighting (multiple keys), then make it a ripple pattern with 4 Tails Cyan. Then hit the Down arrow once every second. That's the general effect I'm trying to go for.

The problem I'm facing is that there seems to be no way to centralize what button you want the ripple pattern to start from.

 

Any suggestions and any help is greatly appreciated.

Thanks for your time.

I can take this request but write it on my request thread for me to remember later and ill put you on my list of requests to do.
