How do I configure Group GPIO interrupt to SCT capture event ?

Hello,
This is first time for me to use NXP MCU.
I use LPCXpresso 1549.

I want to make multi-button logging device.
I want to get the timing of bidirectional edge trigger for 26 buttons.

I think that SCT capture event cannot set a lot of GPIO triggers.
So I want to use Group GPIO interrupt for SCT capture event .
Is it possible?

If it isn't , another way I think is that getting SCT count value in Group GPIO interrupt handler.
But I think that this way has delay for actual counter timing value.

Does anyone have any idea?
Thank you.
