Add ability to collapse/expand case blocks

It looks like Creator offers the ability to collapse/expand the entire switch statement, and other types of code blocks (if/if-else/else blocks, while loops, for loops, etc.), but not the individual case blocks inside a switch block. The user can collapse/expand the entire switch block, but not the individual cases.

So I'd like to be able to make this:
switch(foo)

{ case 0: <case 0 line 1> ... <case 0 line n> case 1: <case 1 line 1> ... <case 1 line m> }

Look like this:
switch(foo)
{
case 0:

{...}
case 1: {...}

}

But it appears all I can do is make it look like this:
switch(foo)

{...}
