Create raw list Schema

How can one create Schema derived class from a list only data?
For input with a field value, i.e. dictionary, e.g.:
{
"string_list": [
"one",
"two",
"three"
]
}
one can use;
class StringListSchema(Schema):
string_list = fields.List(fields.Str())
But how can one so it when input is just a list:
[
"one",
"two",
"three"
]
?
NB: both are valid JSONs

I don't think you can do that with marshmallow. I'm pretty sure there was once a discussion about it, maybe involving sort of merging Schema and Field. I can't find it.
You could probably use a pre_load
to wrap the payload into a dict with a single key and using that key as name for the List field in the schema, but this sucks, of course.
