Unable to set Stylus (.styl) CSS-style autocomplete

Hello!

Stylus language supports both CSS-style

body {
  display: block;
}

and python-style

body 
  display block

of code:

But now in PHP-storm there is no possibility to use CSS-style of Stylus with autocomplete, so Stylus-developers can only use python-style of code. It would be great, if you add possibility to toggle autocomplete style for this language. It is not look hard, because this autocomplete would be almost the same as SCSS-autocomplete

Regards.
