You can create custom attacks in the Central Manager and publish it to the Managers. After creating custom attacks in the Central Manager, you should run policy synchronization for the custom attacks to reflect in the Manager.
Custom attacks defined in the Central Manager are synchronized with all Managers and are non-editable. The Attack ID format in the Central Manager custom attack is different from the Manager custom attack.
A specific Attack ID range within the existing format is allocated to a Central Manager custom attack. Policies are updated in the Manager after custom attack synchronization. The attack name is prefixed with "Central Manager" to represent custom attack policies defined at the Central Manager.
