I'm afraid this is a shortcoming of the software. Hopefully someday it will be corrected, but for now we can only link cut list properties to drawing notes if the note belongs to a drawing view. Your best option (as far as I know) is to save the bodies out as separate Part files, choosing to have the cut list properties converted to custom properties when saving.
Because you can have multiple cut-list items, it would be very difficult to know how to intelligently populate them into the title block. The properties on a given drawing reference a document, not a single body.
Potentially the best way to handle this is add the properties you want into a single Weldment Cutlist, at this point in SOLIDWORKS I think that's as close as you can get.
Depending on the complexity of you title block, you may be able to replace the block with a cut list table or assembly bom.
