Offline Use of satellite/aerial Maps; Understanding caching of tiles

Greetings!

In a few weeks i will be traveling to Sarek National Park in northern Sweden and would like to get my hands on some higher resolution satellite pictures of the area for planning my river crossings. Now, "downloading" an area of the Satellite Map is not possible, but you can cache tiles that you loaded while looking at the map.

I could not find an option like "cache all tiles along my track", so just to understand, is my only option to manually scroll though the whole track so that the tiles get loaded and therefore cached? I guess i would have to do this several times for different zoom levels? Is there maybe an easier solution?

Thanks a lot and greetings from Germany!
