Changing target for social icons

Hi,

I use your great plug-in for social icons, including whatsapp. Great, but it automatically shares the link to the current page, I want it to always point to the homepage.
For example, if I click on the Whatsapp-button while visiting https://www.smartfeud.com/rules this link is being shared, while I want it to share the default homepage.
Is there anyway to override this?

The page I need help with: [log in to see the link]
