TCPDF - Add "Bates Numbering" to merged PDF - php

Question

I'm currently using TCPDI merge four documents into a single PDF and temporarily storing the document using a variable. Is it possible to add "Bates Numbering" to the file, starting with the third page? (The first two pages are a cover letter.) Thanks in advance for pointing me in the right direction
require_once('../tcpdf/tcpdf.php');
require_once('../tcpdf/tcpdi.php');
// Create new PDF document.
$pdf = new TCPDI();
// iterate through the files
foreach ($filesarray AS $file) {
// get the page count
$pageCount = $pdf->setSourceFile($file);
// iterate through all pages
for ($pageNo = 1; $pageNo <= $pageCount; $pageNo++) {
// import a page
$templateId = $pdf->importPage($pageNo);
// get the size of the imported page
$size = $pdf->getTemplateSize($templateId);
// add a page with the same orientation and size
$pdf->AddPage($size['orientation'], $size);
// Set page boxes from imported page 1.
$pdf->setPageFormatFromTemplatePage($pageNo, $size['orientation']);
// use the imported page
$pdf->useTemplate($templateId);
}
}
// Output the new PDF
$attachment = $pdf->Output("Merged.pdf", "S");

I'm not familiar with Bates System but what i did was add the Page number as a Label and check your PageNo variable/index to determine when to show your batesNo.
For the labeling. See the TCPDF documentation.
*Code not tested
<?php
// iterate through the files
foreach ($filesarray AS $file) {
// get the page count
$pageCount = $pdf->setSourceFile($file);
$batesNo = 0000000001; //initialize*****
// iterate through all pages
for ($pageNo = 1; $pageNo <= $pageCount; $pageNo++) {
// import a page
$templateId = $pdf->importPage($pageNo);
// get the size of the imported page
$size = $pdf->getTemplateSize($templateId);
/***********NEW BLOCK*******/
if ($pageNo > 3) {
$pdf->SetTitle('JonesNo-'.$batesNo);
} else {
$pdf->SetTitle($pageNo);
}

// add a page with the same orientation and size

$pdf->useTemplate($templateId);
}
}
