Guided Expand

I REALLY need an input box for expand. I LOVE how expand works compared to rewrite, especially since it reads chapter continuity and story bible, but sometimes I need to be able to explain what exactly I want expanded and more importantly HOW I want it expanded. It would also help with the fact that I am constantly misclicking on Expand while highlighting text and since it has no input box it just instantly starts running and uses credits without me wanting to.
