Multi-currency Account payment in different currency

Multi-currency Account payment in different currency

We have two bank account one in USD one in HKD. I can make payment in USD from both account. My bank allows me to remit from my HKD to a USD account during a Bank Transfer.

The problem I have is when I want to record a Payment to a Vendor in USD the only bank account shown is my USD account when I have paid from the HKD.

Why ZOHO is blocking this and how to go around this unnecessary blocking.

See Picture Showing only USD bank account shown https://www.dropbox.com/s/y3uamj1s2wij8ym/Screenshot%202016-04-24%2013.20.55.png?dl=0

Where here we see my three bank account https://www.dropbox.com/s/a7og9v37lwwvjh6/Screenshot%202016-04-24%2013.22.15.png?dl=0

Looking for a solution for this.
