Circle wipe

Always wondered why there is no simple circle shaped wipe effect in After Effects. Same parameters ar the Linear Wipe, but then in a Circle. 

The Radial Wipe, wipes like the hand of a clock - which is contradictory to the Radial Gradient Ramp, which is circle shaped.

UI-flaws that must be fixed. And pleade add that Circular Wipe, preferably with the option to use local or global coordinates, so shapes can be wiped on their position.
