Currency conversion IMPROVEMENT

I know this has been mentioned before, but no changes were made, so I’m asking again.. Could we please have the option to specify the amounts in both currencies when transferring between currency accounts? Conversion rates differ from place to place, and it would be much simpler to enter both amounts (EUR paid and USD received, for example) and let the app calculate the conversion for us. I constantly struggle getting the amounts correct, and if I don’t want the amounts displayed in the app to be inaccurate then I need to tweak the conversion rates every single time. It’s just a huge pain as it is now.
