Using Sage 50 US Premium Accounting

Several years ago, I created a custom financial statement report. In this report I created Level 2 group totals for several groups. Now I have added a few new expense accounts I would like to add these accounts into existing Level 2 totals. Being sure the new totals are reflected in the "Total Expenses"

However, over the years I have forgotten how I created these Level 2 Groups or how edit these group totals.

Hopefully someone can tell me how to do this.
