[![enter image description here][2]][2] With the **duplicate** group highlighted, choose `Layer > layer Style > Create Layers` [![enter image description here][3]][3] You'll then have a layer for ever style applied. Hold **<kbd>Command/Ctrl</kbd>** and click the thumbnail in the Layers Panel for the Outer Glow to load a selection based upon its transparency.
