Multicurrency

Hi, I’m testing your plugin https://ww.wp.xz.cn/plugins/woofunnels-woocommerce-nmi-gateway/
and I need to put my website with a multi-currency, but I have spoken with NMI support to see if the gateway can be charged in different currencies and they say yes but I have to talk to the creators of the plugin to make the adjustment of it To handle multi-currency, he tells me that the plugin will need to send in the variable “Currency” with either USD or COP or any other currency I wants following this guide https://secure.nmi.com/merchants/resources/integration/integration_portal.php?tid=ca8a332dcff5406ff3cdcc4fe0f7ebe4#transactions_step_1
I wanted to know if you plan to implement it? or what would be the cost of that implementation in my website?
