Multi mode settings for testing materials

I have a template file that I got online by someone else.
This is similar to the LightBurn’s Test Material option, but a bit more in depth.

This is apparently done with multi mode (sub layers), but I cannot figure where the settings are configured (increment of power).
All CO2 (red) layer is 2400 speed, okay. But how to set the 10% increment in power for each of the 4 shapes?

See image.
