Hi, Bonxy

You always can use the old method : use an " OR " gate to trigger one interrupt pin of the device.
after, read ports and just check your inputs as rsocor01 tells, hoping they didn't change state in between ... ( possible issue ... but ...)

note a couple of MCP 23016 or 23S17 ( Port expanders ) could help a lot here ...

the question is here : really need it ???
