Hi AugustusAnnang Thanks for reaching out to us here on the Community and providing us with your valued feedback. We have submitted your feedback to our developers and hopefully they maybe able to implement in the future a function that would enable our customers to directly transfer amounts between foreign currencies. We have also included a link that will enable you to submit your feedback directly: https://feedback.qbo.intuit.com/
As a workaround you could: create a contra/holding bank account in your home currency > transfer the amount from the source account to the contra account > transfer the amount from the contra account to the target account, As we're not accountants we would recommend that you reach out to an accountant to qualify the above information or there maybe a Community member that reads this post that can provide some advice.
