is there a way to specify that a mapped op in a graph uses the docker executor? I can specify that the entire graph asset and job uses the docker executor, so the entire job happens in a separate container, but I'd really like the fanned out op to spin up it's own container for each dynamic output that I want to process
looks like I was able to get the job that the sensor runs to use the Docker executor, which launches each step in a docker container, but I'd love for the asset materialize button in dagit to use the same configuration. Not fully necessary, but very nice to have
