STM32F407 Motor + Encoder interface problem

Hello there,
I am trying to build a stepper motor driver with encoder interface using stm32F4 discovery board. I have already configured and got working the stepper motor interface. For that I used Timers 1 and 8 like in the picture bellow (2 H bridges):

Now I would like to add the encoder interface which consists signals A and B. If I am reading the datasheet correctly for that I need timer 1 and 2. But timer 1 is also used for motor driving... Is there a way to overcome this and have both motor and encoder interfaces implemented?

I would apreciate all help!
