I want to change all date formats in Salesforce to DD-Mon-YYYY (example: 15-May-2020).  I know that I can change the Locale to change the date format, however, in most cases this shows up as 15-05-2020.   I also know I could probably write visualforce pages for each page a date occurs on, but that doesn't seem reasonable.

Is there a way to chagne all the date formats in the system with code (some sort of aura controller?)?
