Shape corners together
Hi, I'm new in Ilustrator and learning.
I have this set of corners that I'm trying to shape a bit more with the direct selection tool, but I was wondering if they could be shaped in the same way at the same time so they end up looking the same.
Thanks!

The screenshot doesn't let me show the arrow, but basically I want to make the outer corners a bit more curved and I'm using the direct selection tool where when I hover over the line with the mouse a little curved line with two squares on ecah end appears.
