How to change the Look of the Map's Name?

So I've saw this in Pokemon Spectrum and the thing is how the name for a map appears in-game it is like in Pokemon BW2 or BW. So I'm asking how do I change the picture that the game uses when the map has the "showarea" in the metadata. I want to change the default look of how the map's name appears. How the name of the map appears when the player enters the area.

Well you can change the "menu frame"/ "ChoiceSkinName" in the "SpriteWindow" script, which also changes the map name graphic.
I'm not sure how to if you only want to change the map name graphic though.

Edit the LocationWindow in the PField_Field script section. Play around with @window.setSkin("windowSkinName").
