Is it possible to have many different system clock configurations using STM32CubeMX?

I would sometimes like to switch to a lower frequency to save power. Is it possible to have many different system clock configurations using STM32CubeMX?

No, as far as I know. The RCC chapter of the reference manual describes in detail how you can switch clock sources while running. Keep in mind that it is not possible to change PLL parameters while the system is running on PLL clock, you have to switch to another source first.
