Adding data for gaps in label availability?

[der2020]

Hey community,

I'm trying to custom-fit a rendition of the Hybrid Reference Layer used in the Imagery Hybrid basemap. I'm working on a copy of that tile layer. The "Continent" layer ("Boundaries"->"Continent") seems to only be visible at Visible Zoom Range = 1 - I've tried adjusting this option (see pics below). I know that the note below mentions that not all data is available at all zoom levels.

Is there a way to overcome this? I am thinking that it would be easy to develop a new layer for continent labels which might patch the data availability issue, but I'm new to the Vector Tile Style Editor and do not know if it is even possible to add data to an extant (copy) of another tile layer. Any insight would be incredible!
