Pin assignemtns for Stacking relay shield v2.1 to run 8 relays

I am looking to run 8 relays, by stacking two Relay Shield v2.1 however assuming both boards are pre-configured the same, how does one set the second set of four relays to be on different pins than the first one?
Did that make any sense?
In other words, are the pins assignable?

You could change the control pins
In the middle of the module, there are four jumper maps.
You could unplug them, and connect I01,I02,I03,I04 to the digital pins which you want to use.
This also will help you, if some pin has been occupied by other module.
