You need to do some coding, if you can then following code work for you.

Now let ‘s copy app/code/core/Mage/Catalog/Block/Product/List/Toolbar.php to app/code/local/Mage/Catalog/Block/Product/List/Toolbar.php (create a new directory if it is not exists).

Open new file and look at these lines of code in around line 232

if ($this->getCurrentOrder()) {
$this->_collection->setOrder($this->getCurrentOrder(), $this->getCurrentDirection());
}

Now, replace with these lines

if ($this->getCurrentOrder()) {
if(($this->getCurrentOrder())=='position'){
$this->_collection->setOrder('entity_id','desc');
}
else {
$this->_collection->setOrder($this->getCurrentOrder(),$this->getCurrentDirection());
}
}

That ‘s all, now remember to clear all cache and reindex too see the magic.
