There are 3 ways of including a budget into a group:
- While reordering the budgets, put them under the budget group name.
- Modify the budget and use the "Put in Group" field.
- Modify the budget group and use the list to put new accounts into the group.
Remember that budgets do not have to belong to a group - it's optional. If you have budget groups, budgets that are not part of any group will always be listed at the top of the list.
