STM32F407: Can TIM2 be configured for encoder AND TIM5 input capture on same pins?

It isn't clear if more than one peripheral, e.g. TIM2 and TIM5 can be configured to use the same pin, assuming of course than both don't try to use the pin in an output mode. If this is possible, then I should be able to capture encoder time transiti...
