Preferred date format EEEE, do MMMM yyyy

Can we have a date format like this EEEE, do MMMM yyyy because it is not in the dropdown list of allowed formats.

I only managed to make it work by adding it to config.edn but when appearing on the Journals page it shows as two separate pages, one with MMMM do yyyy and the other with EEEE, do MMMM yyyy. See the example screenshot below.

In conclusion, the 2 journal entries are distinct and separate. This only occurs after every time it generates a journal template the following day.
