"modifier after tax per bill" shows as discount - remove discount altogether?

[misscherylb]

vm 2.0.6 on joomla 2.5.4

I have set a tax calculation as insurance for shipping, i.e. "modifier after tax per bill".
calculates and shows correctly in total, but also shows the value as "discount". is it possible to remove this?



I've now renamed the "discount" as "adjustment" but not too happy with the solution, is it possible to remove the discount column all together? Like the "show tax in cart" option, but same for discount? Or any other way of doing it? I tried removing it from the coding, but couldn't find the corresponding lines for tax and shipping ...
