If you click the little blue buttons in those slots, the fleet composition you're looking at will be saved to that slot. You can then go to the bottom tab on the left to load saved fleets, replacing whoever's in your fleet at the moment with the saved comp.

So if you have a specific fleet you use for 1-5 or whatever, you can save it for later (top tab) and load it up (bottom tab) without having to pick out each ship individually.
