We are on Appian 7.8 cloud. Following is my requirement. Let me know

Sorry for the confusion here.

Here reports of Manager means people working under the manager. So 3 reports of a manager means 3 people who reports to the manager.

Now, consider following scenario:
Manager A is managing three employees (EmpA, EmpB, EmpC).
Info of EmpA will be stored in AttA, EmpB will be stored in AttB, and EmpC will be stored in AttC. All the Attachments are different excel files.
Now every 24 hours, Manager A will get 3 posts which has information about the employees. (AttA, AttB, and AttC)
Also, EmpA will get a post with attachment AttA. And so on.

Now I am going to use ExportableDatatype (Came with Download Datasubset plug in) to store the data.

So, is there a way I can save the data in the Excel file?
