IoTHub dynamic field names in blob file format of storage endpoint

Question

From the docs it is not clear if it is possible to use message fields, such as device id, and add them to the folder structure of the blob storage. For example we want to save raw data going to the iothub and save it in a separate folder for each unique device. The blob format should be something like:
{iothub}/{partition}/{device_id}/{YYYY}/{MM}/{DD}/{HH}/{mm}.

Is it possible to achieve something like this directly from the iothub?

Even better would be the {routingkey} from the custom routings
