few questions related to currency setup

Hi,

1. I would like to know how to choose currency for a order when manually creating the order within woocommerce? Or at least the currency should be automatically changed to billing country of that customer. But this does not happen.
After creating the order in on hold status, I then have to go again to Change currency on right hand side, as when first creating the order there is no option on right hand side for me to choose currency.

2. Another question: is there any shortcode or hook to display the total amount in the order page (email/customer panel/checkout) in the default currency (no matter the currency used by customer to pay the order)? Or better said how to check currency used and then display the total amount in EUR if the currency of the order is not EUR?
Supposing the customer is from Romania, so currency they should alway use and pay is RON/LEI, but default currency of the woocommerce shop is EUR. And I would like to have this EUR currency as text/informational purpose displayed below the total order in LEI.
Eg. 495 LEI (101 EUR).

I need this information this total in default currency eur to be displayed somewhere in my own custom theme, that’s why a shortcode or hook would be good.

3. Also is any shortcode for the exchange rate I am using (automatic exchange rate) to be displayed somewhere in my theme? is any shortcode for it?

4. I am using wpml plugin where I used to have wpml currency configured. I disabled it, I meand the automatic exchange rate, but for the payment gateways should I leave the wpml setup as it is? the point is to have no conflict between the two plugins (wpml and yours).

Thank you,
Valentin
