NVIC interrupts on two ports with same pin number

Hello everybody,

Is it possible to link same pin number of different GPIO ports on the same EXTI line ?

For example, create an interrupt on line_0 for the GPIO pin A0 and the pin B0. It seems impossible to achieve with the ST librairies - but I don't understand why it's impossible regarding to the internal schematic of the STM32F4... I really want to use more than 16 GPIO with interrupts. Is there a software way to perform this interruption ?

Thanks a lot !
