Paypal vs Hikashop recapitulatif

Hi,

I am trying to work out how to align the syntax for the paypal recaptiulatif with the hikashop (modified from standard). Currently the total column displays the total price including taxes of each article. Then the summary is ordered taxes, sub total delivery followed by final total. hika side , paypal side

However Paypal is taxing the article price with out taxes which is confusing despite the final total being identical. Is there a possibility via hikashop to alter the price used for display on the paypal end? Ideally this would also include altering the titles to completely align the two. Is this possible?

kindly,

Luke
