You can use manual links to create small scenes of actions that belong together. To avoid that these actions are linked by a Select All from unrelated actions, use these symbols in the Dev Title:
"<=" defines the action as entry action for the scene. Select All on any other action will not link this one as predecessor.
"=>" defines the action as part of the scene. Select All on any other action will not link this one as successor.
