AppCode - ObjC document shortcut like javadoc

Hello,
for a new iOS project we are thinking about using AppCode instead of xCode.

Everything works fine so far but I am missing a shortcut to generate e.g. a method stub documentation like via javadoc (Alt + Shift + J).

The "Fix doc comment" function does nothing unfortunately.

So what I basically want to know is, if I had a method like this

- (void) testDocumentation:(NSString *) firstString;
{

}

Is it possible to auto-create the appledoc or headerdoc documentantion via shortcut:

/*
 * Test documentation.
 * @param firstString the first string
 */

Any suggestions would be appreciated.
Thanks in advance
