Probably not. But what prevents you to encapsulate all pins together? Then inside ISR just check which pin caused interrupt as: Mask = myIsr_ClearInterrupt();
That would work. It just looks confusing on the schematic to route pins from unrelated components to the same Pin block.
Alternatively, attach standard ISR components to the hardware connector of each individual pin (do not enable ISR on pin). In this case pins don't have to be on same port.
