Copy JPEG rating to RAWs / How to pair RAW+JPEG shoots

Hello, how can I pair raw+jpeg shoots?

I have lots of directories (C1 session mode) with raw+jpeg shots, but because of historic workflow, only the jpegs are rated. Now I want to copy that ratings to the fitting RAWs. In the directories are also jpeg only shots. Which makes it more complicated. Is their a non manual solution for that?

I hoped to use the raw+jpeg pair function for that, but I cant found it anymore. Is it removed or do I only know it from Lightroom?

EDIT: I have solved that with the new 9.2 function select by filename list.
