Default currency on User preference

Summary

How to make the default currency code be defaulted for any new user based on the Legislation code

Content

We are currently testing the opt in feature delivered in 19B for Expense and related to the Expense approval e mail layout.

We find the new e mail format very nice and clear and would like to activate it for all users.

We noticed that on this e mail format, the amounts are shown in the currency defined by the user on his/her user preference.

This is also a nice idea.

The issue we are encountering is that we seem not to be able to find a way to populate the user preference at the time of the user creation with the currency of his/her country.
