I often find myself stroked shapes for buttons etc (kind of like the "Ask Question" button on this site actually). I follow the approach of creating a white shape with a stroke effect, and then selecting the multiply blend mode. Leaving only the stroke visible. This is a useful technique as i can resize the shape.
So this is fine for the design stage but when it comes to exporting these elements as png's and using them in a website or in after effects, the multiply effect obviously won't be carried over and i'm having to reconstruct these elements in Illustrator. I do this often enough that it's getting a bit annoying.
Is there a different method that will allow me to create these type of elements fully within Photoshop that i can export as fully functional pngs? Without using Stroke Shape, as i can't resize these layers.
Here are some screenshots of the process:
