UMG. How to raise an image for z-order?

Hello all!
I made some UI-screens with UMG. This is awesome tool! And I made a custom cursor with this tutotial: link text. It really helps! But my custom cursor is hidden by UI background image. My answer is: how to raise an image for z-order?
Every object in UMG has a Z-order property, but a custom cursor is drawn by Blueprint and I don’t know how to raise it.
Any help will be great, thank you!
