Gradient Mask Editor - Reverse The Transparency Points

[KF]

Hi,
I am using concentric shape in the gradient mask editor and the preset is the middle is transparent and the outer edge is 100% opacity. Possible to reverse the order so that the middle is 100% opacity and the outer edge is transparent?
Thanks.

@KF There is a reverse order button in the Gradient panel, next to the Color dropdown (a bit different then in the question).
This one will flip the order of opacity values (and colors) along the gradient.

Thank you.
