Not really. Sony needs to put a full resolution JPEG in their RAW files like other camera manufacturers do.
One alternative is to shoot RAW+JPEG and put PM into RAW+JPEG viewing mode and PM will show you the JPEG instead of the RAW but will treat the two images as one for any editing you do in PM (IPTC captioning, rating, tagging, color labeling, cropping, rotating, etc.)
