Visual divider in between batches

Create a visual divider in between multiple added batches.

When I adding multiple batches to render to multple folders, I need to change the output path for added files, but it is hard to distinguish which files belong to each added batch.

In addition, it would be nice to set the output path for each added batch before the files or Comps are added, in stead of selecting all and then set the path (with long lists and scrolling this is an error sensitive process).

(I know there is some kind of facility in Preferences, but that is too rudimentary. I would rather see a filebrowser/dialog to set the path at the moment of adding files)
