How to get smithy-format to keep resource identifiers and properties on separate lines

[mcmasn-amzn]

I have a smithy file like this:

resource PackageVersionTag {
    identifiers: {
        name: PackageName
        tag: Tag
    }
    properties: {
        version: Version
    }
    put: PutPackageVersionTag
    read: GetPackageVersionTag
}

When I run smithy format, it condenses identifiers and properties like this:

resource PackageVersionTag {
    identifiers: {name: PackageName, tag: Tag}
    properties: {version: Version}
    put: PutPackageVersionTag
    read: GetPackageVersionTag
}

Is there a way to configure the formatter to avoid compressing these sections? I find it more readable to have the original code with line-breaks in it
