Add to draw 2D figure ( unfilled rectangle, circle, ellipse..)

I want to draw 2D figure( line, unfilled rectangle, unfilled circle, unfilled ellipse… ) in front.

I drawed line by Draw2DLine function, but it was hided by UMG Widget.

I drawed rectangle by DrawRect function, but it was filled by color and hided by UMG Widget too.

I drawed rectangle by K2_DrawBox function , but it was not applied line color.

And I can not draw circle, ellipse.

Please add to draw 2D figure having priority property.
