interlock mode + timer

Is it possible to use interlock mode in a way that after a button is pressed all relays turn off after a certain time?

So I press A, relay 1 is on, relay 2 is off, after one second, both off, if I press B relay 2 is on, relay 1 is off, after 1 second both are off (without having to press another button)

Sorry it seems it is not possible on our current receiver.
I’m afraid you might need to use external timed relay module, and use our remote just as a momentary trigger.
