Impossible to export textures to multiple psd files

This seems to be there on purpose but it has been annoying me since the beginning of Painter. Why isn't it possible to export textures to multiple .psd files, just like exporting .tga files? The exporter will always ignore the export preset and will just export only one .psd file with a bunch of layers. Why would that be useful? At first I thought this must be a bug, and nobody cared to fix it. But it is even noted under the exported maps:

This makes no sense to me. Please make this setting optional. I would prefer to have the choice of using .psd files like any other fileformat.
