Is this possible to refer multiple buckets_path in `moving_fn` aggregation?

Elastic Stack Elasticsearch
1

official doc introduces moving_fn syntax as below.

{
    "moving_fn": {
        "buckets_path": "the_sum",
        "window": 10,
        "script": "MovingFunctions.min(values)"
    }
}

then, is this possible to refer multiple buckets like below?

"moving_fn": {
    "buckets_path": {
        "foo": "foo",
        "bar": "bar"
    },
    "window": 10,
    "script": "MovingFunctions.sum(params.foo.values) + MovingFunctions.sum(params.bar.values)"
}

It seems not works. I got an Error like below

[moving_fn] buckets_path doesn't support values of type: START_OBJECT"

but I wanna confirm centainly this isn't possible. thanks in advance
