Options for preferring hanging indents with one item per line when formating lists

I would like to add options/code so that yapf can be configured to prefer outputting something like

MyLongNamedTuple = (
    something.somethingelse,
    something.somethingelse,
    foo=(
        bar.somethingelse,
        something.asdfas,
    ),
)

over

MyLongNamedTuple = ( something.somethingelse,
    something.somethingelse, foo=( bar.somethingelse,
    something.asdfas),)

Any news regarding this feature? We are heavy user of vertical lists and it would be a much appreciated option to have.

Probably the best thing that can be done here is to use the heuristic that if the list ends in a comma then we will try to place them on individual lines. Otherwise, we will do “bin packing” on the items in the list.

MyLongNamedTuple = [
    something.somethingelse,
    something.somethingelse,
    [
        bar.somethingelse,
        something.asdfas,
    ],
]

as opposed to:

MyLongNamedTuple = [
    something.somethingelse, something.somethingelse, [
        bar.somethingelse, something.asdfas
    ]
]
