I agree, this is definitely something I want to add! Expect it relatively soon, in a smaller update I'll release before I start work on the Sex update.
I don't know if its already a thing, so far it doesn't seem to be, but I'd like it if the feeder also decides how long you are going to be in the autofeeder for, and sometimes lies and adds more time slots afterwards as well. Like say she convinced me to get in it for one time slot but then adds a whole day or even a week to it, with a chance of it being repeatedly added to.
