Rotate items vertical

[Skyline]

Hey guys,

Probably a really simple question, but I can't seem to find a way for it. I would like to use those new magnet blocks in a few maps and I was wondering how it's possible to rotate my blocks vertically e.g one that a normal booster is upside down.

Arrow keys and NumPad + and - rotate items. Standard blocks can't be rotated as far as I know.

Now i feel dumb, haha. Thank you so much!
