Starting show by slow fade in from black?

It seems like this should be simple, but the best I can do is start with a blank black slide, set duration at the minimum allowable (.8 seconds), and then use a long dissolve transition. This isn’t exactly what I want because there’s a bit of delay before the image starts to appear. Is there a way to start a show with a fade in to an image from black without using a black slide and transition?

You can’t change the initial (fast) fade from black, I’m afraid.

Thanks for the answer. To me, this seems like a serious shortcoming in the program. It’s a pretty simple and often-used technique for the start of a show.

I don’t think it’s a serious shortcoming to be honest, many people like it that the show starts from black, but we consider to build in an option for that in the future.
