Implementing a few key features can significantly improve the user experience, particularly for large organizations dealing with a substantial user base and multiple entities when assigning security roles under a user's profile.

Add check box against each entity and select all check box in the header:

Firstly, consider introducing checkboxes next to each entity. Additionally, include a "Select All" checkbox in the header, providing users with the flexibility to easily toggle the selection status of multiple entities. This enhancement will streamline the process of granting access to various entities, contributing to a more efficient user experience when selecting organizations for a user and role.

Add the Entity code along with the name:

Furthermore, incorporate the display of Entity codes alongside their names. This addition will assist users in swiftly identifying the correct entity for selection, given that entity codes are commonly utilized across various sections of the system.

Undo and discard the changes.

To address potential errors, incorporate an "Undo" or "Discard" feature. This functionality allows users to retract accidental selections of multiple entities, enabling them to revert to their previous selections and maintaining a sense of control over the access-granting process. These improvements collectively contribute to a more user-friendly and efficient system for selecting organizations for users and roles.
