Display specific currency when customers select payment method

Hello,

I just bought your WooCommerce Multi Currency Premium plugin.

I would like to setup following conditions below:

My default currency is USD.

1. At checkout page I would like to show USD when customers select Western Union, Bitcoin, Payoneer and show THB when customers select Treepay. (I need to setup like this because the Treepay support THB only.)

Please see a picture here: https://prnt.sc/1arxiwc

How can I setup this?

2. I use WP Fastest Cache Premium plugin.
Do I need to add “define(‘WPFC_CACHE_QUERYSTRING’, true);” to wp-config and setup default customer location to “Geolocate with page caching support”?

Please help.

Please excuse my poor English.

Thanks
