Support ISO 8601 date format (and others) in JO emails embedded reports date fields

I’m working on a digital engagement journey (JO) which contains an embedded report in an email with a report that contains date fields.

Everything’s fine when building. It displays per our locale preferences. And come email testing time. The date is displayed in US format in the email: mm/DD/yyyy.

Needless to say that:

1. The US format is NOT universal (it is used by a vast minority of countries)
2. dd/MM/yyyy seems to be used across the majority of countries
3. yyyy/MM/dd (and variants with hyphens) is the most universally understandable format, and happens to be, in its hyphenated format, the INTERNATIONAL STANDARD (ISO 8601)
4. The US format is problematic whenever the day (dd) ranges from calendar day 1-12 (which can be confused with the month (mm)). How do you know what day and month the following date really is: 03/04/2026 ? Is it the 3rd of April or the 4th of March? 

So we have a product that forces the date format of a minority into reports that are embedded in JO emails. 

I am puzzled by the approach to default to a non-universal format.

But more importantly, the product needs to be upgraded to support the majority of this planet.

Allow us to choose date formatting in Reports that are embedded in emails. This is not a nice to have. It is a must have to communicate effectively with our customers, wherever they are, and without imposing a confusing date format onto them. If that cannot be done, the default MUST be the international standard. Not the minority format.
