Rectangle TOP to Rhombus shape

Hello guys,

I have a rectangle TOP and I want to reshape it into a classic Rhombus-shape(the corners have two narrow angles and two wider angles).

Right now, I am going to substract 2 rectangles from each other and combine 2 of the new triangle shapes, to get my Rhombus.

But is the a faster way to go from simple rectangle to Rhombus?

another way is to first rotate 45 degrees and then change scale of one axis.
For this to work, set transform order of the Transform TOP to Rotale, Scale, Translate

Yes, thank you!
