Inability to honor Multiple Currencies on the C360

I have a customer that has customers with multiple currencies in their Current ARR field (on their account object) as you can see in the following screenshot: 

However, when I try to display that field in the C360 Summary as well as the Attributes section in the C360, the Current ARR only displays in pounds, which is this customer's default currency in SFDC. 

This is obviously an issue because it shows a customer with a $50,000 contract as a £50,000 contract. Big difference. 

At the very least, this issue needs to be addressed, and I understand from Support it's an enhancement request.

I'm also having an issue when trying to load their Current ARR field to the ARR field on the customer info, which I would like to do in order to utilize our revenue band feature.
