Expenses Workflow approval 9.2

Is there a way to make sure the Expense Report is fully approved before moving to the next stage?

Example:  We have an Expense Report with 3 lines.   Line 1 requires a Review approver.  Line 2 requires approval for department 1.  Line 3 requires approval for department 2.

What we see happening is that the Expense Rpt may show up in Preaudit approval queue  after for each approval.     We can not define the number of approvers needed more than 1 because department 1 or 2 may have multiple individuals assigned to the department to approve but only 1 required to approve.
