LDAP Generator with eDirectory

I would like to create a web page for users to search for a user object in eDirectory and add an attribute to the user object if it doesn't exist or update the value of an attribute if does exist.

I have come across a few obstacles:

1.  Data types are limited to one object class.  What if I want to display attribute values from more than one object class?

2.  I don't see an update component with the LDAP Generator?  I only see add attributes, add entry, delete attributes, delet entry, and search.

Any help would be greatly appreciated!
