Bulk Imports with elements that have multiple values

I’d be grateful if someone could provide a little clarity for me please. I am trying to get my head around doing bulk imports either via Batch Uploader or CSV Import. Some of the elements may have multiple entries which you would traditionally enter via “Add Input” for the given element. It appears that CSV Import supports this by using a delimiter between multiple values, however, its not clear if Batch Uploader supports this. Can anyone add any insight for me please? Thank you!
