I have spent a lot of times poking around editor trying to do this so far I have come up with nothing.
I would like my the order Fleet Commanders to be able to board the Death Star (like Eaw) and the Executor.
I am a all eggs in one basket kind of guy. I always try to keep my ships with Heroes safely in the back. Playing standard it annoys the shit out of my that my Fleet Commanders and Palpatine are in a separate Star Destroyer, it means I have one less Star Destroyer I can use aggressively. I love how the all the Rebel Heroes ride on the Home One.
Standard Hero attachment order: Star Destroyer, Admonitor (Thrawn), Accuser (Piett), Arc Hammer, Victory Destroyer, Acclamator Cruiser, Interdictor, Tartan, Shuttle
