Please refer to WT-8848.

We support date formats - which appear to be redundant (see first two) and incomplete.
MM/DD/YYYY
MM-DD-YYYY
YYYY/MM/DD
YYYYMMDD

But not - which is one of the standard US date format.
MMDDYYYY

This date format picker needs to be rationalized to allow following regular expressions where * stands for any special character. In fact the list can be further pruned if the system could parse the string to remove special characters first and then we interpret it for only three options.
MM*DD*YYYY
MMDDYYYY
DD*MM*YYYY
DDMMYYYY
YYYY*MM*DD
YYYYMMDD
