I assume you would want something integrated to Admin CP, but well it's not a 2 min. hack so here is my fast solution:

Edit forumdisplay.php, find:

PHP Code:

$thread[typeprefix]=$stickythreadprefix.$thread[typeprefix]; 


Replace it as:

PHP Code:

if ($thread[threadid]==X OR $thread[threadid]==Y OR $thread[threadid]==Z)
{$thread[typeprefix]='STICKY:'.$thread[typeprefix];}
else
{$thread[typeprefix]=$stickythreadprefix.$thread[typeprefix];} 


Replace X, Y, Z with the threadid of threads that you want to have "sticky:" prefix.. Others will be prefixed with your admin cp specified prefix..

Enjoy
