Raw and JPEG pairs in Capture 1

I sometimes have to shoot JPEGs along with raw files. Nikon NEF, Mac, not that that matters. I'm used to editing, captioning, keywording in in Photo Mechanic (and Lightroom) which treats the two files as a pair. So when I star rate (for example) an image the metadata is applied to both the raw and JPEG files.

How do I do this in Capture 1?

Thanks!
