Enable "Select all / Deselect all" when assigning policies to employee groups

Currently, each policy must be manually selected or deselected when assigning them to employee groups. With 20+ policies, this is time-consuming and not user-friendly. Certain groups like for e.g. the ISMS governance council needs to read all policies, which is not optimal.

Proposal: Add "Select all" and "Deselect all" buttons to quickly assign or remove all policies with one click. This would save time, reduce errors, and significantly improve the user experience.
