Massive Actions

sometimes we need to make massive creations og Groups, Users, Entities and So on...

It's possible make a plugin or native functionality for make massive actions like that?

I mean something like a form with this:

ex: Option: combo box

-------------

* Users

* Groups

* Entities

* Categories

....... etc.

if the option it's user then appear something like:

User 1

id - password - entitie - Profile

User 2

id - password - entitie - Profile

User 3........ and so on.

if the option it's group then appear something like:

name - entitie - subentitie - etc.....
