Payment Method by Domain

Hello! I have a website hosted with different domains depending on the country it is showed. So it is the same website, only with different domains.

i.e.:
- example.co.uk for the UK
- example.eu for the rest of europe
- example.ca for Canada

But all of them points to the same website.

For each of those countries I have different PayPal accounts, so I want to create 3 "HikaShop Paypal payment plugin" with the three different PayPal accounts but I need them to be restricted to the domain I select.

Let's say:

i.e.:
- example.co.uk for the UK [must show my UK PayPal account]
- example.eu for the rest of europe [must show my German PayPal account]
- example.ca for Canada [must show my Canadian PayPal account]

I know that can restrict it only by Zone or Currency. Just I don't want PayPal to know that I am using more than one account in one domain. For example, if a UK citizen knows about my site and in Canada, he will buy in example.co.uk but will pay to my Canadian PayPal account.

So, I want if the client visits example.co.uk, will pay to my UK PayPal account doesn't matter where he is located.

I'm sorry for being such a long message, just want to be explained as clear as possible.

I know this function is not built-in in Hikashop, so is there someone you can recommend [expert in HikaShop] that I can contact to develope this function?

Best regards,
