datepicker/calendar input template or a pipe

[Et3rnal]

Can we have a date template please?
Here is what I'm trying to do: the dates I get are in ISO format, the backend expect ISO from me, however the user will see the date based on the configured locale, so I have the option to turn the ISO date string to date object and back and worry about the timezone etc.. which I don't want worry about

So I'm using dataType="string" without dateFormat
Now my only issue that I have to convert the dates from ISO to the locale string when loading, and reverse that when submitting.

However if there is a way to separate the displayed value from the actual model value then no transformation required.
I was thinking maybe a pipe, template, allow dataType to take a function or a [displayType] propriety etc..

Please let me know if there is a way Im missing, I had this with other libraries and it saves time and avoid mistakes
