Alphabetize author names in blog dropdown

Hi! I run a site for the local news outlet Waterbury Roundabout out of Waterbury, VT. We have a number of reporters & community contributors, and as such, many 'basic authors'. When selecting the author for a new blog post, I find that the dropdown of our contributors is completely randomized, neither alphabetical nor chronological. It is alphabetical in 'settings'>'permissions', but not the dropdown for some reason (see photo). Does anyone know of site functionality to alphabetize this list in the dropdown specifically? If not, is this something that Squarespace could address in a future update? It would be a big help - thanks in advance for any tips!

Please see the following for a workaround.

Let us know how it goes.
