Photoshop: Apply mask to selected layers
In my job, we quite often need to apply a layer mask to a psd containing lots of layers/folders. Currently the only way to apply the same mask (for example a mask of the entire workspace) is to either apply it individually to each layer, or to create the mask on one layer and alt-drag copying it to the next layers. It would be a big time saver and less fiddly to be able to select all the layers needing the mask, and then when you hit the mask button, it applies to all selected layers. Seems like something so simple, so I'm wondering why it's not possible?
