Imagine there is one customised OL Map defined.
There are multiple Views data overlays on the site.
And there are different Views pages or blocks.
If you want to reuse your customised map for all the pages and blocks, but only show one Views data overlay per page / block,
how would you make this possible?

I think it would be great if I could configure the OL Map in a way that the layer visibility comes from a setting on the Views page / block.
Any thoughts?

Now I only see the possibility of cloning my OL Maps and chose one layer per map and select each respective map in the different views pages and blocks.
