Sravani — my thoughts on this, below — although I’d have thought you’re about as stage 3 as it gets :-)
As for scheduling publications, I do think the platform could make some improvements, like letting authors schedule when a piece goes live, independent of it being accepted into a publication. Last I checked this wasn’t yet possible.
It also helps to cultivate relationships with pub chiefs — in my experience they are some of the nicest & most hard-working people you could meet. Some will be accommodating on when to publish a piece if you reach out ahead of time, but of course their time & generosity shouldn’t be abused, given that they are basically doing this pro bono.
