I can create a component that will be possible to add to the assets pane using:

[Component(
  Categories = "cms",
  PlugInAreas = "/episerver/cms/assets")]

I can also add it to the default group in the assets pane, the one with blocks and files, using:

[Component(
  Categories = "cms",
  PlugInAreas = "/episerver/cms/assets/defaultgroup")]

All good. However, as a user I would like to group two components that developer-me has created in a custom group, like the default group. Unless I'm missing something, user-me can't do that, right?

Given user-me can't do that grouping developer-me would like to do that for user-me. I've accomplished that using an IViewTransformer inspired by Linus' post. Developer-me is glad I can do that, but would like an easier way to group components. For instance by specifying a group in the Component attribute.

Is there such a way?
