Can I create lambda step from ecr image by using Lambda class in lambda_help.py?

Describe the feature you'd like
Hey! As I read from the code in lambda_helper.py, I only see Lambda class wrapped creating lambda function from a script. Is there any reason it does not support creating function from ecr images?

How would this feature be used? Please describe.
should be a parameter that I can refer to the image uri:

Lambda(
        function_name="function_name",
        execution_role_arn=params["pipeline_steps_arn"],
        image="image_uri"
        handler=step_config["handler"],
        session=session,
        timeout=step_config["timeout"],
        memory_size=step_config["memory_size"],
        runtime=step_config["runtime"],
    )

Currently, I did in this way (from boto3 lambda client call):

response = lambda_client.create_function(
            FunctionName=function_name,
            Role=params["pipeline_steps_arn"],
            Code={"ImageUri": step_config["image_uri"]},
            PackageType="Image",
            Timeout=step_config["timeout"],
            MemorySize=step_config["memory_size"],
            Architectures=["x86_64"],
        )
        return Lambda(function_arn=response["FunctionArn"], session=session)
