Override price in product's currency

[q-styler]

Hi!
I'm having a store that keeps its prices in Euros but trades in our local currency.
Some of positions are on sale. So I have to specify `product_override_price` for them which is kept in euros as well.
But that overriden price is set in store default currency, not the currency of the product.
I think that's sort of a flaw and should be changed in future.
