Photoshop :: Name Merged Layers According To Original Bottom Layer's Name Instead Of Top?

I like to keep my layers carefully named. I often create new layers over existing ones to build up effects and paint in details. When I merge these layers, Photoshop always assigns the new merged composite layer the name of whatever the topmost layer was. I would much prefer it to default to naming the new layer whatever the bottom layer was called. I'm using CS5.5.
 
I might start with my assets in a file, with layer names like: Model, Field, Product, Logo, etc... Then add effects on layers called, Shading, Highlight, Package Detail, Lettering, etc... over each original layer. When merged, instead of being named the more-appropriate names, it will of course use the top layer names and I end up with my layers called "Shading, Highlight, Package Detail, Lettering. It's made much worse when I duplicate effects to modify and apply to multiple layers, then merge, leaving me with a file with layer names "Highlight, Highlight Copy 1, Highlight Copy 2, etc..." Renaming to my original layer names is very tedious as a result.
