Put [Return] items first in Sierra Madre vending machines

[chance2now]

I'm not sure if the menus for the Sierra Madre vending machines can even be modded like you can mod store & player inventory displays, but if it is possible, I would love to see the [Return] options at the top of the list in these machines. That would make it easier to turn in a big haul at the BOS bunker. Even better would be a single menu item to return all returnable items with one selection. Thanks for your efforts!
