Way to generate supports inside of a model with bottom layers set to 0?

I have a model I am trying to print without a bottom layer so its hollow. but it has some overhangs I need supported. But Orca thinks it still has a bottom and wont generate supports inside. Is there a way to tell Orca to generate supports inside of a hollow model?
