Currency Conversion configurations and default display currency

[BryanGC]

Hi all,

I'm in need of a currencies configuration option help.
I work/sell in an unsupported currency, (N$) NAD, This currency is pegged 1:1 to a supported Currency (R) ZAR.

I've noticed that the system has an issue with pricing from registrars, as it imports the prices incorrectly. for example; If I look up a .com domain, it will give me the price as R14 ZAR (and the pegged N$14 NAD), instead of the converted price from $14 USD (should be around N$252).
How would I get the system to perform that conversion properly? I've thought about setting the default currency to USD and then letting the system perform the conversion that way, But I then Cannot Peg my NAD to the ZAR to get correct pricing.

Another thing I'd like to do is have the WHMCS frontend display everything in the NAD currecy as a default, it there a method to to this?

Any advice or resources you can point me to would be a great help, as I'm not a developer or coder.
