Add Existing Items to Regions - Adding Underscore

Hey guys,

I'm trying to add regions from one project to another. I'm using the Add New item wizard and I noticed that after I added the image, I noticed that Test Complete added an _png to the image name. Is there a way to add images to Regions without the underscore? It would be tedious to have to remove it with each image added.

Side note: I'm guessing that Test Complete adds the _png because it converts Region images in png format?

Thanks in advance!
