APA Style Guidelines 7th Edition

Could I ask when Endnote will produce a style for the updated APA Style Guidelines 7th Ed. I just received my copy of the guidelines today. I thought I would just update my existing APA 6th style (which I had modified anyway to be fully compliant with the 6th Ed), to produce a 7th Ed. version. However, under Bibliography->Author lists there is the option: “If eight or more authors, list the first 6 authors, insert: ,… and add the last author’s name”. In the APA 7th Ed. this has been modfied to 21 authors. But there is no option to vary the number of authors for this option. Is there a solution to this in the existing version of Endnote? Or will a new style file for APA 7th be developed?

Many thanks.
