Service tax in PLD

Dear Experts,

I have created a PLD for A/P invoice. This is an item based service invoice where the service tax has been linked to every item. Now i want a break up of the service tax i.e 10% , @ % & 3% in the footer level. Is is necessary for me to create a new repetitive area?? or is it possible to get the break up at the end of report itself.. Kindly guide me with the necessary steps

Regards

Shyam
