TinyMCE: Alphabetical order for lexicon entries when creating hyperlink

I am using Modx 2.8 with TinyMCE Rich Text Editor with several Lexicon Entries. Whenever I want to insert a hyperlink in a text element, I click on the “insert hyperlink” button and “choose resource” button where I select “lexicon” which once again opens a new from the popup context menu. Unlike the screenshot below, my entries are in random order which makes searching for specific topics time consuming.


How can I instruct modx to sort all entries in the list in alphabetical order?
