Add custom currency

Hi,

https://docs.easydigitaldownloads.com/article/272-adding-currency-support-eddcurrencies

I am following this tutorial to add a new currency, in my case I am adding Colombian weight, but I do not want it to be displayed as follows: COP 2000, I want $ 2000 to be displayed, I can only add the code, but not the Symbol.

With this plugin, if I can do it, but besides being outnotted, it seems more practical to add the code directly to my site.

How can I add the Symbol to my Custom Currency?`

Thx
