You just need to put in the colonize ability for each type and make sure the the number of abilities match up:

Example (requires all three colony types researched):

Name := Multi Colony
Description := Materials needed to start a colony on any planet.
Pic Num := 114
Tonnage Space Taken := 200
Tonnage Structure := 200
Cost Minerals := 2000
Cost Organics := 1000
Cost Radioactives := 1000
Vehicle Type := Ship\Base
Supply Amount Used := 0
Restrictions := None
General Group := Colonizing
Family := 5002
Roman Numeral := 0
Custom Group := 0
Number of Tech Req := 3
Tech Area Req 1 := Rock Planet Colonization
Tech Level Req 1 := 1
Tech Area Req 2 := Ice Planet Colonization
Tech Level Req 2 := 1
Tech Area Req 3 := Gas Planet Colonization
Tech Level Req 3 := 1
Number of Abilities := 4
Ability 1 Type := Colonize Planet - Rock
Ability 1 Descr := Can colonize an Rock based planet.
Ability 1 Val 1 :=
Ability 1 Val 2 :=
Ability 2 Type := Colonize Planet - Ice
Ability 2 Descr := Can colonize an ice based planet.
Ability 2 Val 1 :=
Ability 2 Val 2 :=
Ability 3 Type := Colonize Planet - Gas
Ability 3 Descr := Can colonize an gas based planet.
Ability 3 Val 1 :=
Ability 3 Val 2 :=
Ability 4 Type := Cargo Storage
Ability 4 Descr := Provides 20kT worth of cargo space.
Ability 4 Val 1 := 20
Ability 4 Val 2 := 0
Weapon Type := None
