Hi there,
You can do this using advanced actions and user variables.
you can create your own variable and apply a default value of 0.
On exiting the normal slide assign that variable with the value of 1 or if you have a button on that slide then you can apply action on that button.
and on enter of the slide you can apply a conditional action.
to check the value of that variable if it is equal to 1 then go to next slide, else continue.
