Agent template for all user

[Cognos8]

ETL tool loads data in to datamart everyday. I have created generic
event to  ensure data is loaded or not. Once it is loaded report will be executed and send it to specific user. Here i have 500 + user , each one wants to use same event but different report.Also new user and report may get added frequently.

I have proposed 2 approaches and wanted to know your comments for any other better option.

1. User can copy this event and create task.
2. User has to reach admin to add their report in to generic event, so that report will be triggered to their respective user.
