[Suicide Junkie]

You give the order, and the ships immediately follows it. The order is complete, and dissapears from the order queue. There is then nothing to repeat!

Just move the ship around until it has zero MP.
Then give the orders and press repeat.

You will lose some time if the first destination is less than 1 turn away.
As was described before, you can also just do the repetition manually: when the ship runs out of MP, check the orders, fill in the missing bits, and press repeat.
