Hello,
The reason these two modes do not exist for Cuety / LPU lies in the fact that Cuety does not work with so called sub-fixtures.
In this case, the LEDs on the ball are divisible in either two zones, back and front, or can each be addressed individually. Resulting in multiple RGB dimmers, where only one can be controlled by Cuety.
If you need all of them to work, for your project, then we can possibly make that happen, but this will involve patching more fixtures in Cuety to control just the one physical fixture.
Let us know!
Cheers,
