Add Contact to Target List

Question

Is it possible to add a Contact to a Target List while in the Account Screen or Contact Screen? 
 The use case is that we are going to do a Customer Sat survey and I need users to go to an account and choose the specific Contacts the survey should go to and then add them to a Target List.

Harald Kuske in theory it is simple to add such drawer. 
 Lets get ListLayout as an example: 
 $viewdefs['base']['layout']['list'] = array(
 'components' => array(
 array(
 'view' => 'massupdate',
 ),
 array(
 'view' => 'massaddtolist',
 ),
 array(
 'view' => 'recordlist',
 'primary' => true,
 ),
 array(
 'view' => 'list-bottom',
 ),
 ),
);

Now lets look at SubpanelLayout 
 $viewdefs['base']['layout']['subpanel'] = array (
 'template' => 'panel',
 'components' => array (
 array (
 'view' => 'panel-top',
 ),
 array (
 'view' => 'subpanel-list',
 ),
 array (
 'view' => 'list-bottom',
 ),
 ),
 'last_state' => array(
 'id' => 'subpanel'
 ),
);

So we may need to add view massaddtolist between panel-top and subpanel-list and inherit the code which manage its rendering.
