Ability to wake up from analog signal rising above a threshold level?

Hi, we are considering using an STM32F7 microcontroller however we need to establish whether or not a microcontroller from this range would be able to wake up from a low power mode from an analog signal rising above a configurable threshold level.

I understand that a rising or falling edge on a WKUP pin can trigger an IRQ which wakes the device up, however I need to clarify if this can be extended to wake up the device only when the input signal rises above 2V for example (and for that threshold to then be reconfigured to lets say 2.2V dynamically).

This seems like a great range but we need to ensure that it can meet specifications before we can use it. Hopefully someone can shed some light on this.
