How Can I Grant Specific Permissions to a User and not to the Whole Role?

In Smart145, permissions are usually given to whole roles, not specific users. However, it is possible to provide these for only one user if a new role is created for the desired permission and that role is added to the user as complementary to those they already have.
 
1- Create a new role for the desired permission in Security>Roles:

2- Add the desired permission or permissions to the new role:

3- Add this new role to the ones the user already has by editing the user in Security>Users:

Now, the user will have these permissions. Please notice that this solution is meant for granting complementary permissions to a user who already has a role.
