Let me quote myself from another thread where someone also asked for better automation in EVE:
You have two options already: use the existing automation and spend a little more, or manually time the command bursts yourself.
I like to manually press command bursts myself when the fleet needs the shield resists and similar, so I never get a weapons timer at the wrong time.
And for mining boosts… well I just keep them running all the time. I prefer being lazy over spending less ISK. It’s a tiny difference anyway.
