Inverted wave, zig zag, with the "Outline Zigzag" shape effect

[Subpath]

Would it possible to extend the "Outline Zigzag" shape effect a bit
by adding a option for a invert a wave, zig zag in the end
it should look like the Pic below

As it is by now a inverted wave with this effect is possible
be change the direction of a path

But i though it may be easier to use if there where a
invert option in the effect it self.

Of course 2 Paths are needed, one with the normal and
one with the inverted effect

@Subpath I added this to the backlog.

For closed shapes it is possible to "shift" the overlay shape.

The 3rd image is a bit more complex, as it has the intertwine effect.

@VectorStyler

thank you
I have already tried "shift" on open paths, but that didn't work,
so it only works on closed paths.

The interwine effect of the 3rd image, the circle, is not needed.

That was just an example of what would be possible. I created it
with the shape builder forgot to mention it
