I second the recommendation to use the Node Wrangler addon.  Then all you have to do is press CTRL + SHIFT + T shortcut, it will open your file manager where you point to the folder where your PBR textures for whatever material you are trying to create exist.  Select the maps you want to include in the material.  For example, the color, glossiness, roughness, bump, and displacement.  It will automatically import those maps and place them into a node structure as they should be set up.  Couldn't be easier.
