Use Shopify Markets, but disable currency conversion

I would like order to use USD, which is the store currency.

I have Shopify Markets enabled so I can limit which countries we ship and generate analytics.

For the Markets I have defined, I can set to USD and all is good. For the other Markets, that are not specifically defined, Shopify is converting to their native currency. I would like them to display in USD, any suggestions?

Others have solved this by deleting Markets, but I would rather not do that.

Got the same behaviour. Anyone has an idea on how to fix this?
