The graphics bank is 128x128 pixels while the actual screen is 256x240 pixels, so not really. You're really just making all your assets in the bank that you can paint onto the screen. I guess you COULD just make a 128x128 graphic for your start screen, but that would most likely waste a TON of graphic space that could be used for more assets.
I recommend you use Shiru's NES Screen Tool for special screens instead of NESmaker's special screen tools. NESst is a lot better suited for it.
