Can we add multiple currency in an estimated?

Glad to see you in the Community, @finance-flextran. Let me share a few details about adding multiple currencies on estimates in QuickBooks Online (QBO).

I can see how the benefit of being able to create an estimate transaction with two currencies would aid you in running the business with QBO. However, for the time being, the option to do so is unavailable.
