STM32G431: control 4 stepper motors with TIM1's 4 PWM channels?

I'm considering STM32G431 for a motor control project with 4 stepper motors driven by step and direction.

Can all 4 steppers be controlled by using TIM1's four PWM Generation channels 1 thru 4 and be made to move by different amounts of pulses simultaneousy?

Or do I need to use a separate TIMx for each motor, e.g., TIM1, TIM8, TIM2, TIM3?

You need a separate timer for each motor, unless you want them all to move at the same speed.
