Name of the region on the pins

One feature I couldn't find on Wand's Where Winds Meet map is filtering by region. Although the regions are separated by color, I can't type the name of a region into the filter to bring up all the pins in that region and hide the pins from other regions.

This makes it much easier when we are trying to complete The Sages, get 100% of each region, you stay focused only on that region and ignore the pins from others.
