Can carriers be simulated properly?

Isn't there a cargo button in the simulator setup screen? SE4 had it, and I can't recall offhand if SE5 does, but I seem to recall it.

In the simulator there is a button labelled I think "Set Cargo" which you can use to load fighters into your carriers.

Is your carrier part of a fleet? I was confused at first when my ships didn't appear to respect their strategies, but then I realized that the fleet's strategy was overriding the strategies of individual ships. Now I typically have a couple different task forces in a fleet in order to assign multiple strategies (e.g. I'll use a task force set to Capture Planet for my transports, but everyone else is in the primary task force set to Short Weapons Range).
