Two separate white brightness slider

Hi, I have configured an Esp32 with a analog white LED (PWM white) on the first pin and on the second pin a Sk6812 RGBW LED Strip.

The configuration works fine.

My question is:
The white brightness slider change the value from both white LEDs (PWM + Sk6812 ) together.

Can I configure a second white brightness slider? So that the PWM has an own brightness slider and the Sk6812 for the white LED an own brightness slider.

Thanks

Set them up as separate segments.
