group quotation template - how to code a grand total that isn't repeated for each group heading

Hi all,

New to Sugar/Suite but enjoying delving into the experience! I am trying to use the quote group template but I am running up against a problem where I have added in a grand total at the very bottom of the quotation. However, Suite seems to be taking this and adding a total under each group of products and services I have created. Can someone tell me what to insert after the group section so that it doesn’t repeat the values please? Thanks!!
