I'm flying LHR to DEL return in December. Was looking at EY flights with a 1-2 night stopover in both directions. When searching for flights, the booking system prompts you to add a stopover, but with a toggle for adding it either on the outbound or the return trip.

Is it possible to take advantage of the stopover package and/or transit connect package in both directions? I can't find spot any terms and conditions that indicate it's one-direction only.
