Do you mean 'canvas'?

If so, I think the answer is 'no'.

What affect do you want to add?

You could create a completely black sprite and use memblocks to make the transparent sections, and put it over the entire screen. Although this method would make rendering very slow on a phone

I have been looking into doing something like this myself but I have not managed to find a way yet. The way im thinking about doing it right now is to cover the screen with a black sprite then place white sprites where I want things to be visible and render everyhting to an image. Then I would use a fullscreen shader and pass the image to the shader which would cover the black areas but leave the white areas covered. I am just waiting for AppGameKit v2 templates for VS2010 before I will try it since it requires both the new fullscreen shaders aswell as the render to image command.

As for performance, I have no idea how well it will run but im mainly targeting PCs so im hoping this method would not take to much effort for the GPU.
