Reducing draw Calls

Hello,

currently im workin on reducing draw calls in my uGUI.

But since uGUI renders the objects accordingly to their hierarchy, this process is pretty weird.



So i put each Text in a seperate Canvas and checked override sorting.

But now each single Canvas generates a new Draw call

So how can i fix the drawcall order (first the images, then the text, usually this are 2 draw calls), without destroying the hierarchy ?

Best regards
