Is there any real point in designating a colony as 'mining', etc?

[Marvin Kosh]

Does this mean we can make our own files, so the ministers are actualy useful?

i.e. we could designate our own 'blueprint' for a farming colony design, if we really don't need much organics and would rather use the space for a heckuva lot of research facilities or storage. Then we just have to actually select it. In simultaneous games I get annoyed that the AI picks the wildest sort of function for my colonies. Maybe I want to designate my new colonies myself, at the start of the turn they were colonised.... kinda hard to pick them out when they already have one set....
