Consider renaming layers with ambigous titles

Reminded me that we have a problem with layer titles being ambigious without the context of the layer groups. Many tools in QGIS only display layer titles in dialog boxes, so a user is stuck with trying to figure out what e.g., a layer titled "January" is (which is a layer under the "Median extent" layer group, which is itself under "Sea ice")

I feel like this should be raised to a QGIS issue. Can they simply improve those dialog boxes to show the whole group hierarchy context as "breadcrumbs" or something?
