Outer Glow Edge Matching

I was recently creating an image and it came to the point that u needed a subtle outer glow for it. I tried using the outer glow layer style, and while it looked okay for the area of the color I chose, it didn't look so great in the others. I looked online for a way to make the outer glow match the edges of the layer only to find that it did not exist. The closest I could get to emulating the effect was to make a copy of the layer and put it underneath, then give that copy layer a Gaussian blur. It worked well enough, but I feel like it could be way easier to have a selection in the outer glow section for "Match Color of Layer Edge" or something along those lines.
