Multiple Employer Reporting

I'm the manager of a team of 6 with over 700 employers and need the ability to report on:

1. Open tasks for all employers.

2. Dashboard warnings (payroll warnings, pensions warnings RTI warnings etc) for all open.

3. Payroll Frequency - All employers

4. Processor - who is assigned to what employers

5. Paydate - what is the paydate for all employers

There are many more to be listed but these are my top five for now.
