I’ve (I admit to this now only because I was young and ignorant, and now I’m old and clever…ish) done numbers 1 and 2. Number one because I thought it’d save time for when they (obviously) requested my full ms. Number two because I just knew they’d fall in love with my sci-fi even though it was clearly a romance list I’d submitted to.
