how to snap anchor points on the panel ?

pic on the left - where anchor points are

pic on the right - where I want them to be

I can manually pick every anchor point and put it in place. but is there an easy way to do it ?

You can use this Anchor Snap | GUI Tools | Unity Asset Store . It is free. I further modified that asset to be used from the cog from the RectTransform component in the inspector.
