catalog of JPG images - apply attributes to RAW images

I've shot some images with CamRanger importing the JPGs and auto imported them to Lightroom so clients could view and select images right away on the spot.

My question is, how can I apply these attributes -- star ratings, color ratings, even crop info -- to the RAW files for later processing?

For speed purposes, we only had CamRanger send over the JPG files and built the original catalog only with JPGs. Now I want to apply those selections to the original RAW files.

thanks!
