is there a way to set the `io_manager_key` for graph backed assets or `multi_asset`s?

I found the answer: `@multi_asset(outs = {'asset_name': Out(io_manager_key = my_io_manager)})`

yep that's correct -- just a heads up that passing regular `Out` objects to the `outs` parameter is deprecated (it should be `AssetOut` instead)

<@U01J51Y6B9D> may I ask how to specify partitions for multi-assets?
```@multi_asset(
    partitions_def=daily_partitions,
    required_resource_keys={"my_client"},
    outs={
        "asset1": AssetOut(
            io_manager_key="json_io_manager",
            key_prefix=["raw"],
        ),
        "asset2": AssetOut(
            io_manager_key="json_io_manager",
            key_prefix=["raw"],
        ),
    }
)```
When I materialize this, I got the error msg:
```ValueError: Tried to get asset partitions for an output that does not correspond to a partitioned asset.```
