How to update the value from a field with a copy of the value from another field

-- HikaShop version -- : 3.4.0

Hi Hikashop team,

I'm busy creating a CSV export for UPS Worldship software.
UPS told us that it's better to not use the state field, only when the package has to be sent to the United States of America or Canada.

So I have create a custom field "order_ups_state" and I want to update the value with a copy of the value from "address_state"
only when the shipping address_country is United States of America. So in all other cases this field will be empty.

So I have create this Mass Action.
The only question I have is how to update the value for "order_ups_state" with a copy of the value from "address_state".

Hope you can help me with this issue.

Oké thanks, I'm going to investigate this option.
