Is it possible to configure rendering area under the "spyglass"?

[adamsss92]

Hello,

I've created a story map, using "spyglass" template. I'm using two maps which have got WMS service layer as the background map. Is it possible to configure rendering area under the "spyglass"? I want to avoid "tile loading effect" when i'm moving the spyglass across the map.

I know that it's WMS cause, but maybe it is possible to force "spyglass" to load a larger than "spyglass" area during the its movement (tile caching?).

Additional question - is it possible to change spyglass size from the story map creator level (via website)?
