Hi there,
Not fully defined, would you want those links to load in current tab, or still open them in a new tab but remain on the same page? For the second one, it would probably take a browser plugin, but if you want those links to load in the same page then a small chunk of JS will do.
Price for a plugin would be $45, price for JS which will load them in the same tab $25
If you can define which of these you need I will update my bid and we can do it.
Regards,
Julijan
