World Editor Creator Question

Anyone know of an easy way to collapse some of the "directory" tree in the world editor creator without moving the data files around?

For instance under Interiors there is just one "folder" called fps with one folder under that and so on until you come to another Interiors folder. So it looks something like this:

|-Interiors
 | |-fps
 |   |-data
 |     |-Interiors
 |       |-Test
 |       | |-etc.
 |       +-Myr
 |       +-evil1
 +Shapes
 +Static Shapes
 +and so on...

I'd like to collapse the second Interiors folder into the first one to make it look like this:

|-Interiors
 | |-Test
 | | |-etc.
 | +-Myr
 | +-evil1
 +Shapes
 +Static Shapes
 +and so on...

I know this is a pretty minor thing to change but if it's not too hard to change it will save some time for the level editors -- so they don't have to click through all the folders again and again.

Thanks,
Mike
