Hi:
Are you talking about updating an existing Excel sheet with your paneling? That's not a possibility with ODS -- generally, ODS wants to create your FILE= file as new each time you run your code. So, for example, you could not create the "data" on Monday and then, on Wednesday, just add the second piece of the report.
When you talk about paneling, would you be adding a table or a graph underneath the "data" portion?
