As far as I can see, this seems to be one of the many things that was removed in the switch from VB6 to C#. I'd imagine it will be re-added in a future patch.
Is there a way to repeat a set of fleet orders a certain number of times? I know you can cycle orders but that repeats until it can't anymore and the repeat orders button just doubles to current order list making it difficult to transport a specific number of installations. I feel like I'm missing something obvious but any help is welcome.
