Second "Attachment" for a Notes Record

We don't do custom coding... (I'm looking for a way to do this without custom coding)

In the Notes Module, there is a field named "filename" with a Field Type of "File" and a label of "Attachment".

I'd like to be able to have two files attached to a note, but the field type "File" isn't an option in Studio, and cloning the existing field isn't available.

Is there a way to have two (or more) attachments for a given note?
