I have some catalogs without separate identifiers. I have custom columns for each one I use for the most part, but some of the catalogs don't have the individual columns for identifiers like "goodreads" or "amazon", and I need them separate so I can import the list easily.

So, can I create a composite column "identifiers" and import that column in the catalog? That's how I do it for individual columns.
