If Possible to Read existing PDF content position and add the some content after over the existing content in laravel?

Laravel Package: "setasign/fpdi": "^2.3", "setasign/fpdf": "^1.8"

$pdf = new \setasign\Fpdi\Fpdi('L','mm','A4');
$pageCount = $pdf->setSourceFile(public_path().'/'.$url);
$pdf->setFont('Arial', 'B', 10);
for($i = 1; $i <= $pageCount; $i++){
    $tplIdx = $pdf->importPage($i);
    $pageDimensions = $pdf->getImportedPageSize($tplIdx);
    $pdf->addPage($pageDimensions['orientation'], $pageDimensions);
    $pdf->useTemplate($tplIdx);
 }

If It Possible read the content of the last page and get after page content ordinate of the current position. then Write new content without add new page or whitespaces
