Please go easy on me, as this my first post

The totals in OpenCart checkout appear as below and this is ideally how I would like them to be transferred to Paypal:
Product $13.00
Sub-Total $13.00
Shipping $6.00
Tax $1.95
Total $20.95
When the totals are transferred to Paypal however, the way the totals are displayed changes to the layout below:
Product $13.00
Shipping, Handling, Discounts & Taxes $6.00
Item Total $20.95
Total $20.95
Is there anyway of stopping Paypal from displaying the "Shipping, Handling, Discount & Taxes" as one total and have them display exactly as they were in OpenCart with shipping, tax and potentially any discounts, separated out into their respective totals.
I am sure there will be someone who has wanted to do this before, and perhaps I am entering incorrect search terms when searching the forum, however I haven't been able to find anything on the topic so far. I apologise in advance if this post is tedious for the experts on the forum but your help to resolve this little issue would be hugely appreciated.
