What is the functionality to create report tree for copa reports

Dear Fellow members,

Good day to you!

I would need your advise on how to create report tree for the list of COPA reports created by users in Production. Note that currently power user is using KE30 to create these reports. Due to its sensitivity, I need to prevent users from knowing the list of reports created. Basically just wanted to allow user to execute the few copa reports revelent to his area like Channel P&L.

Many thanks in advance & cheers.. !
