Script - Rename Artboards + Number suffix

I added a {fn} placeholder to my BatchRenamer script to insert the filename after reading your question. The original artboard name is deleted from the Find & Replace fields.

/*
This script will rename the artboards in the active document by using the name of the document and adding a suffix number. 
The suffix number will have a fixed width of 2 digits and be zero-padded if necessary. 
For example, if the document name is "Myfilename.ai", the first artboard will be renamed to "Myfilename 01", 
the second artboard to "Myfilename 02", and so on.

function artBoardName_serial() {
  var doc = app.activeDocument;
  for (var i = 0, l = doc.artboards.length; i < l; i++) {
    // THIS IS WHERE THE RENAMING HAPPENS
    var suffix = (i + 1).toString();
    while (suffix.length < 2) {
      suffix = "0" + suffix;
    }
    var newName = doc.name.replace(".ai", "") + " " + suffix;
    doc.artboards[i].name = newName;
  }
}

function renameArtBoard_MAIN() {
  if (app.documents.length == 0) {
    alert("No Open / Active Document Found");
  } else {
    artBoardName_serial();
  }
}

renameArtBoard_MAIN();
