Setting GPIO interrupts for two identical pins

We are developing a software application that uses GPIO interrupts.
We want to set interrupts on the same pins (PE8, PG8), but only one of them can be set to external interrupt mode in the ioc.
Is it not possible to set external interrupt mode for two different ports on the same pin?

    Architecturally it's not possible even if you enabled them in FW. Only one will physically interrupt.

    Thank you for your reply.
    We understand that this is a physical constraint, so I will close this.
