[TYPO3] How to get a TCA Type

[tapio]

Hi

I would like to use TCA, which is use in the bottom
of the alt_doc.php

It has
  General options:
      Hide:   Start:   Stop:  Access:
				 Selected:    Items:

  Access:
Selected:    Items

is for selecting FE groups.

I would like corresponding for BE groups.
Default options in kickstarter doesn't have it.

Using 'database relation'
creates this kind of config


			'config' => Array (
				'type' => 'group',	
				'internal_type' => 'db',	
				'allowed' => 'be_groups',	
				'size' => 10,	
				'minitems' => 0,
				'maxitems' => 10

That works but it is not as handy as list on the right.
