changing the columns of the checkout header

at the checkout header I have two problems

1.  under the Anzhal column I cannot set the unit of measure appear (peace; m2; etc) 

  1. it would be nice to see the price per unit net +Enthaltene MwSt.

 (which you can see in the example under

(now I only have just like in the demoshop Anzhal + Enthaltene MwSt.+ Summe)


1 Can we add the unit of measure next to the numbers in the anzahl column?

2 can we change thte enthalten mwst coloumn to price per piece?
