You don’t actually need to call BA, just search for economy and use the stopover facility and you’ll see Y, PE and J availability on the long haul and ET plus CE options on the domestic leg. You can then select which cabin you want on each sector.

This is also useful when you want to fly to LHR the night before a long haul trip but have it all on one PNR.
