When clicking on the LC a UI pops up which shows how many rockets are ready to launch (with cargo). A button Launch All and a checkbox for Automatic Launch.
Since it's actually kinda awesome to see several rockets launch in a staggered fashion it would be cool if the Launch All command would stagger the launch effect.

Cost ... uhhhm - same as rocket silo?
... honestly I would be happy with just automatic launching, building and keeping a bunch of silos supplied is decent endgame fun.
