So I have been trying to do some custom factions, in the base game (version 3.02 presumably).  And I have noted a couple of problems.  Any suggestions for fixes or work arounds?

1 - when I edit a faction and set a Tech tree, it seems to set/save that tech tree to ALL the factions or at least all the custom factions (using the Faction Designer front end) .  This is a major problem say for synthetic factions that no longer have the right tech to replicate.

2 - I have alternate ship sets availible in the Ship Designer screen, however when I go to the Faction (Civilization?) Designer, only the standard Ship Styles are availible in the drop down list. Why are they one place and not the other?  In particular why are they not where I need them to get the alternate ships to be used?
