I would like to have a feature in LDAP Studio where I can modify the same attribute of multiple entries. For example, currently I want to use eduPerson object class for all person entries in my DIT. So I want to add eduPerson as a value of objectClass attribute to all person entries in my DIT. And then I also want to add eduPersonAffiliation attribute to all eduPerson entries with appropriate values. So the value of this attribute will be "student" for all students, and "employee" for all employees. To be able to do this I need a selection mechanism. For example I can select a container and I may want to modify an attribute of all entries in that container. This applies to my current DIT design because all student entries are under a Students container.
BTW, this feature has nothing to do with subtreeSpecification based selected.
