Does anyone know a way (presumably undocumented; at least I can't find anything in the Lightroom manual or on Adobe's support site) to export multiple smart collections -- for example, a collection set containing a group of smart collections. I'm referring to exporting the rules for the collection sets, not the image files identified by the logical selector(s). What I'm trying to do is create a single output file that can be used to transfer the rules for N collection sets to another catalog in one go, without having to manually create all the individual lrmscol files from the source catalog and import them to the destination catalog.
