CodeFolding - can it be manually forced?

Code Folding seems to undo itself more often that I'd like.
Is there a way we can define a section to auto fold?

I picture something like this

<? php
class foo{

    // region: utilites, folded: True
    function IDontEverWantToSeeThis(){
       //junk
       //clutter
       //bad code
    }
   // endregion: utilities

?>

If there was a way to do that, so that PHPStorm would open this file with that region collapsed, that would be awesome
