How do I credit or debit a group of users?

The Users context in Pharos Administrator has options to credit or debit the account of a single user, and batch operations to credit or debit all users. How do I change the balance of a group of users, but not all of them?

The user batch operations (Credit, Debit, Set Balance) are affected by filters. If you have a filter set, the operation will only apply to those user accounts that match the filter. (Filters are configured and set using the Toggle Filter and Set Filter buttons on the User context toolbar.)

For example, to credit the accounts of all users in a particular User Group, set a filter that specifies the desired group for the User Belongs to Group property. To credit only those users whose are billed in advance, select "Advance" for the Billing Option property.
