No, PowerStore does not offer this functionality. It can be added using eCart, but there will be a lot of code that will need to be modified by hand to make it work, it is not a supported feature.

the basics of quantity discounts is to create a new calculation called truePrice:
([Quantity] > 10)?([Price] - ([Price] * 0.1)):[Price]

You then need to modify the Total Price Calculation from
([Price]-[DiscountShown]) * [Quantity]

to account for the discount:
((([Quantity] > 10)?([Price] - ([Price] * 0.1)):[Price])-[DiscountShown]) * [Quantity]

the AdjustedPrice calculation also needs to be changed:

([Quantity] > 10)?([Price] - ([Price] * 0.1)):[Price]-[DiscountShown]

The truePrice calculation will be used to display the item price to the customer, the TotalPrice calculation will be used to calculate the cars sub total.

This is where the code of PowerStore needs to be manually edited

In all of the checkout pages:

You will need to find any place where the price is displayed using:
<?php echo WA_eCart_DisplayMoney($WA_Store_Cart, $WA_Store_Cart->DisplayInfo("Price")); ?>

<?php echo $WA_Store_Cart->DisplayInfo("Price"); ?>

and change it to use the truePrice:
<?php echo WA_eCart_DisplayMoney($WA_Store_Cart, $WA_Store_Cart->DisplayInfo("truePrice")); ?>

<?php echo $WA_Store_Cart->DisplayInfo("truePrice"); ?>

you will also need to edit the Local checkout code that passed the price, and change that to pass the truePrice:
$AuthNet_itemized[0][$nextIndex] = "Price";
$AuthNet_itemized[1][$nextIndex] = "".$WA_Store_Cart->DisplayInfo("Price") ."";

$AuthNet_itemized[0][$nextIndex] = "Price";
$AuthNet_itemized[1][$nextIndex] = "".$WA_Store_Cart->DisplayInfo("truePrice") ."";

there may be other places it needs to be changed as well, the reality is there are simply to many places the price is used for me to be able to account for them all.
