No decimals in pricefilter

-- HikaShop version -- : 3.2.2
-- Joomla version -- : 3.8.3

Is there a way to remove the decimals in the pricefilter when i have the "dynamic display" option on.?

Now it show 0,79 - 149,95
We have cursor steps of €1 so it moves to 1,79.. 2,79.. 3,79....

We would like to show it as:
0 (always round down) - 150 (always round up)

Thanks i found a way to do it.
But is there a way to override this file so it won't be lost with an update?
