Report Queries - footer, export, filter

Hi everyone,
I have some queries about the report. Can someone help me with this:

  1. How to add text in the report footer.

  2. How to export a report of dynamic name. For example: I have a report “Resource Allocation Report”. I want to export this report as "Resource Allocation Report {employee_name}.

  3. In the report filter, when the user selects the employee_id, I want to show employee_name along with employee_id.

  4. How to add a condition on a column in the report that does not export.
