CSV import for multiple files

We have multiple files to associate with some of the records we are importing. Can we add references to all desired files by including their web paths as comma-separated values in quotes?

Or, is it only possible to import one file per item using CSV import?

Thanks very much!

Edit: I see now that multiple files per item are possible with CSVImport.

I've been tripping up on the pros/cons of Dropbox vs. CSVImport. A combo of the two should do the trick (upload files to Dropbox, call out as many URLs as necessary per item in our CSVImport spreadsheet).

Then, in a perfect world, we'd still be able to batch-edit items and reference multiple Dropbox files per item. Maybe this is possible...
