Anchor more than 2 target

I used to use NGUI before switching to uGUI. You can anchor a widget UI to more than 1 target (no need parent) with NGUI. But If use uGUI, I just can anchor it to parent only. I want to anchor my widget left to object A and anchor right to object B. So anyone deal with it?

Look like this anchor system below

 

Up ! No one needs this feature?

 

Depends on what you want to do, you can generally recreate what you could do with multi target anchors by using the new layout system.

For example, if you want a UI element to fill the horizontal space between 2 other UI elements, you could place those 3 elements in to a horizontal layout, give each of them a layout component and enable flexible width on the middle layout component. That'll get it to fill the gap between the other 2 elements.

 

But I don't put them to the same place, they have difference parent so can't use layout element
