How to make "et al" appear in in-text citations in APA 6th

Hi Leanne,

I am a brand new endnote user, so thanks in advance for your patience.

Under “Author Separators” I only seem to have 2 options.  Is there a way to create a 3rd option?  This is what I am trying to achieve:

2 Authors:

Always cite both authors’ names in-text everytime you reference them. Example: Johnson and Smith (2009) found…

3-5 Authors:

Provide all the authors’ last names when you first refer to a document with 3-5 authors. Only list the first author with the Latin abbreviation “et al.” for any subsequent references.

Example:

   Jones, Chavez, Jackson, and Chen (2010) duplicated…

   Jones et al. (2010) further described…

6 or More Authors:

If a document has six or more authors, simply provide the last name of the first author with “et al.” from the first citation to the last.

Example:

   Thomas et al. (2007) likened abnormal psychology to…

   … distractions (Thomas et al., 2007).

Important Note: If you have two or more documents that look the same when shortened, please follow the guidelines set out in the Authors and Dates Matching section.
