What about symmetry in liquid filter mode?

Hi. My name is Kris Hosea and Im a concept art student. I saw that symmetry found its way into Photoshop, which I think is great. Now you can do all sorts of shapes and not worry about mirroring it. That made me think, because I was drawing a face, and I use liquid mode alot because its so creative and easy to adjust the shapes.

What Im missing is symmetry mode in Liquid. If you adjust something, everything that has the same shape language, it would be useful to be able to adjust both sides at the same time. Saves alot of effort, time and it could be alot of fun. Tell me what you think???
