Proliferation Ability

I created a custom civilization and gave it the Proliferation ability which creates 2 ships instead of 1.  I would like to request that, when the ships are created:

1. if there are no ships already in the cell where the new ships go, the 2 new ships automatically become a fleet.
2. if there is already a fleet in the cell where the new ships go, the 2 new ships get added to the existing fleet unless the maximum logistics would be exceeded.

The reason for this request is that I queue-up a large number of ships to be produced and it is very tedious to have to manually combine the resulting stack into a fleet after each turn (I give the first ships in the fleet the "Sentry" order so I do not have to deal with them every turn until I max-out logistics for the fleet).

I also noticed that, if producing a ship requires resources (i.e. Durantium, Elerium, etc.) you only have to pay for one ship, the second one does not cost any resources.  Is that the intended behavior?

Finally, I noticed that when you create Treasure Hunters you only get 1 (not 2).  Is that intentional?  If so, does that apply to all "Mission" type ships?
