Help with changing actors to alpha=0 with user defined area

Hi GS community this is my first post on a specific question about my game after reading through the how-to's and forum for couple of weeks. I am learning a lot of all of you! That being said. I have a game mechanism I can't figure out how to approach.
I know how to make actors transparent in the background after an event (collision from another actor). But my real question is how can code such that actors within a user defined area becomes transparent?
Example: The game starts with a player (cursor) on a white background. The white background is actually consist of many squares of white blocks that covers the screen. I want to be able to have user draw a shape using the cursor and have all the white blocks within the area turn to transparent and not just the ones that actually collides with the cursor.
Any guidance is appreciated,
Thanks
