Secondary Currenrcy in Product Price

[admin]

One could use the previous price section in the edit product, then use CSS to remove the strike through characters on the frontend. You might need to build a child theme file for the product details though to add things like 'US' or 'CAD' where you need...

Is there a way to set/configure/code a secondary currency price on existing items? E.g. The main price for the products is CAD $10, and then underneath the main price, show the alternate currency price e.g. US $7.30.
I know that you can configure the currency in the store and allow users to pick a specific currency, but looking to have the same price in two different currencies, 1 the main currency and the second price in an alternate currency.
