[Closed] Deposits

Background of the issue:
I am trying to configure my store so that the order remains in the store currency (US dollars) by default, but the buyer sees the price in their currency at the time of payment. Currently, if the buyer changes the currency to their own, the order is created in that currency. I want the order to be created in the store currency, but the buyer would pay in their currency with conversion before payment.

Symptoms:
The order is created in the buyer's currency if they change it, instead of remaining in the store currency.

Questions:
Is it possible to make the order remain in the store currency by default while allowing the buyer to see the price in their currency at the time of payment?
