Sales Report Breakdown

Is there a way to break down the expression

[Sales:1, 1]
{REPORT TICKET TYPES:!PreOrder && TotalAmount >= 0}

I want to add another expression that is to be shown under the sales:

@{REPORT ORDER DETAILS:O.Total.sum:(MG=Bread)}

Isn’t there a breakdown by goup on bottom of work period report?
