Adding template hooks to existing profile tabs

[Chris8]

There is no plugin for that, I've simply added a new template hook to profilefield.php in addmin panel

$category_locations = array(
	''                    => $vbphrase['only_in_about_me_tab'],
	'profile_left_first'  => $vbphrase['main_column_first_tab'],
	'profile_left_last'   => $vbphrase['main_column_last_tab'],
	'profile_right_first' => $vbphrase['blocks_column_first'],
	'profile_right_mini'  => $vbphrase['blocks_column_after_mini_stats'],
	'profile_right_album' => $vbphrase['blocks_column_after_albums'],
	'profile_right_last'  => $vbphrase['blocks_column_last'],
	'profile_newhook'  => $vbphrase['newhook']
);

Then I used it in the end of "memberinfo_block_contactinfo" adding

$template_hook[newhook]

And it works I mean it works if I use it in "MEMBERINFO" template, but it doesn't work when I use it in "memberinfo_block_contactinfo".
I must be missing something obvious here.

Or maybe there is an other way to add specific fields category with it's fields to that tab? Note that I need to add category, not fields themself.
