Chance order of bibliography on Endnote Basic

I am using Endote Basic with the Cite-While-You-Write plugin for Word 2010.

My bibliography is sorted by order of appearance of the citation in the text. However i need it in alpahbetical oder.

I found multiple threads concerning the topic, which essentially boil down to

“From the Edit menu, choose Output Styles and select Open Style Manager.”

In my version however, the “Edit” button seems to be missing, i can only change the whole citation Style (e.g. “JAMA”), which leaves the order of the bibliography intact.

Is there any way to achieve this with Endnote Basic?
