My mother always said, if you don't ask, you don't get!

If you're so desperate for visual approaches, and are happy to take them, what's wrong with asking?? If you don't ask, you don't get, how am I supposed to know you're visual when I'm sitting in a darkened room with no windows??
Maybe try it out once, if it's a no, I'm sure you'll get a good reason, if it's a yes, we're all happy and it negates any problems with legalities of offering visuals.
