[wp-hackers] Bulk Actions?

[Frank Bueltge]

Hi at all.

I think it is current not possible to add custom bulk actions, only remove
entries of the bulk actions.
// This filter can currently only be used to remove actions.
 $this->_actions = apply_filters( 'bulk_actions-' . $screen->id,
$this->_actions );

Give an idea to add a solution to add custom bulk actions, especially on
custom post types or has a reader of this list an default solution, without
include via javascript?
Thanks for read this and give a reply
