Open Link in Same Tab

If you're comfortable with vanilla Javascript, you can add this on your exported page within a script tag. It seeks out any anchor tags with a specific domain and swaps out the "_blank" target attribute with "_self". I've put a timeout on it, because even though I'm firing this after the DOM loaded, it didn't seem to work without a delay.

var domReady = function(callback) {
 document.readyState === "interactive" || document.readyState === "complete" ? callback() : document.addEventListener("DOMContentLoaded", callback);
};

domReady(function(){
 setTimeout(function(){
 var nldLinks = document.querySelectorAll("a[href='https://yourdomain.com/']");

 for (var i = nldLinks.length - 1; i >= 0; i--) {
 nldLinks[i].setAttribute("target","_self");
 }
},1000)
 
})
