Timesheet - Options

Hi all,

I have all the Administrator rights to edit PWA settings and I wanted to check if there is an option in 'Timesheets' to apply the changes to the what checkboxes can be ticked/unticked across the tenancy as an admin? I tried looking for option in Server Settings but no success. For eg: I am trying to get rid of the 'Planned' task option across the users. How can I do it please?
