How to disable or corrupt "all" on pagination?

-- HikaShop version -- : HikaShop Business: 2.2.1
-- Joomla version -- : 2.5.14
-- PHP version -- : 5.3.16

I have a lot of products in the store. How to disable the ability to show "All" in the selection of pagination? (only from the front, of course!) (eg show 10, 20, 40, all) - How to disable or corrupt "all". The shop is not able to display 4000 products, it takes a very long time, and the user goes.

Hi,
One of the solution will be to edit "getLimitBox()" function through the "administrator/components/com_hikashop/helpers/pagination.php" file and change this line :

$limits[] = JHTML::_('select.option', '0', JText::_('HIKA_ALL'));

//$limits[] = JHTML::_('select.option', '0', JText::_('HIKA_ALL'));

Works. TNX!
