Set Selected layers as (svg/png/jpg/none)

[fr32c]

Sometimes, after preparing my files properly, i'd love to export (again) only a subset of layers, I'd need an option to "set selected layers as"

So far, I can set all layers or set items inside layers. First option is too "wide", second option goes inside the layer and changes the first item's extension, but not the layer's name, hence I'd have to move all to layers, but then need to rename…

Start from:
layerIWant.png
layerIwant.jpg
layerIdontwant.png
layeridontwant.jpg

would like an easy way to:
layerIWant.png
layerIwant.jpg
layerIdontwant
layeridontwant

(of course, i have more than 4 layers…)
