Can koha admin generate patron-card without making a batch (Tools › Patron card creator)?

I was looking for a feature that administrator can generate the patron-card directly from Patron detail page.

During my code browsing I found two files 'print.pl' and 'create-pdf.pl' in 'patroncards' folder. Good thing was there was already a GET parameter 'borrower_number' (@borrower_numbers) that seem to be used to generate the PDF for a list of borrower.

So, I think there is/was a feature from where i could chose a list of patrons without making a Batch.

This code also seem to have a bug!

I didn't find any online browse-able code therefore a snip-it from create-pdf.pl is here:

    grep {
        push(@{$items}, {item_number => $_});
    } @borrower_numbers;

'item_number' itself is not used anywhere. 'browser_number' is used to retrieved this data.

foreach my $item (@{$items}) {
    if ($item) {
        my $borrower_number = $item->{'borrower_number'};

When I replaced second with the first one, it stared to generate the pdf
