I doubt that.
However as a couple of others have asked, provided one is able-bodied (and not a small child), isn't it easier (and faster) to walk down to the galley and ask for a drink, snacks or in the lady's case a toothbrush? I also don't understand why she wouldn't have a wet bag with toothbrush, small 100ml or less toothpaste and other vanity items in her backpack of small bag? I regard it as essential, as along with a change of clothes it would help enormously in the relatively rare event of a diversion or other severe timetable amendment.
