WooCommerce Points and Rewards

I can’t find a currency switcher which is compatible with Woo P&R. The currency switchers change the earned points as well.
e.g. 75GBP product should earn 75 points. Customer converts currency to USD = approx $100…the points earned change to 100.
This can mean that customer has higher value points because they earned at a higher conversion value and can redeem at a lower one, effectively gaming the system.
Please allow stores to switch currency for products and checkout transactions – but for all P&R transactions to be based off store base currency.
