Beside what @DaveR suggested…
You can hide the Tags by desired Scenes without extension like on the animation below:
-
Actually when the “Scene Update” popup appears it is “enough” if the Visible Tags tick-box marked.
-
When you select the Scenes, left mouse click with Ctrl or Shift can be used as usual, at least on Windows …
You Can use similar technique with the Outliner Tray for components / groups.
