Autocomplete in Smarty templates

Hi, is there any possibility in PhpStorm to have a code autocompleted in Smarty templates?

e.g.: I have PHP project, where autocomplete works fine and in Smarty template (*.tpl) I'd like to write this:

{* @var $variable Some_Class_That_IDE_Knows *}
{$employee->}

Ctrl + [space] and, voila!, all methods from Some_Class_That_IDE_Knows class are suggested! :-)

Am I missing something in settings or writing it badly or it's not possible?

Thank you, Tom
