author terms list

How do you enter variants for author names using the author terms list?
Is this the best way to handle multiple versions of the same author
name?

The Journals terms list seems more intuitive because you can enter
variants in different cells. For the authors terms list, however, you
only have one big text box with no further instructions on whether all
variants should be entered in the same place and how they should be
separated (e.g., using commas, semi-colons?). Information for using the
authors terms list is vague in the help manual.
