Update all EmbeddedDocument at once

Here is my models.

class Attachment(EmbeddedDocument):
    path = StringField(required=True)
    is_deleted = BooleanField(default=False)

class Test(Document):
    test_id = SequenceField()
    attachments = ListField(EmbeddedDocumentField(Attachment), required=False)

Until now, to set is_deleted=True all embedded document, I used below code.

test = Test.objects(test_id=test_id)
for attachment in test.attachments:
    delete_attachments(test_id=attachment.test_id)

def delete_attachments(test_id: int) -> None:
    Test.objects(
        test_id=test_id,
    ).update(set__attachments__S__is_deleted=True)

Is it a only way to update all document?

Is there any update_all method here?

Thanks.

No repository file, test, or entry point is identified in the issue. First inspect the existing update behavior for EmbeddedDocument lists and determine whether a bulk update is supported; done should be a documented or implemented way to update all embedded documents, with coverage for the shown Attachment case.
