[Scripting Question] Making the Signpost Appear in the middle of the screen?

So I was wondering if there was a way to make all the signpost appear in the middle of the screen, in a diffrent font, bigger letters, and then just fade away. I think it would look really cool, and allow more custimization depending on the location.
Kinda like this:

The first thing that comes to my mind is that you would probably edit the script that handles signposts and make changes to it. If you want to just show an image that contains the text you can show it as a sprite. That is probably the easiest solution. If you want to be able to just type freely what should be shown, your best option would be a bitmap font

The wiki said it was under the section pokemon_messages, but I cant find that section. I barley know any Ruby so I might just show a picture. Sorry if i sound stupid, but what exactly is a bitmap font? I know the game has fonts in a folder. The script couldnt be that hard to mod though, just changing the cordnatits it uses to 0,0 should fix it, an making the little window box dissapear....

The signpost class is class LocationWindow in PField_Visuals. Stuff gets moved in between versions sometimes.

Well, to center it by changing the x y value to 150,150. Is there a way to set specific fonts depending on the location?

Never mind, solved the problem.
