[Flow] Multiple inheritance for models

[Falk]

Hello guys,

I've a model "bill" which has a lot common properties of referenced models (e.g. model "address" and model "costLocaction") for archive purposes (instead of referencing). What is the best way to avoid "duplicating" the model properties (traits)?

model: bill
---------------
property
property1 of address
property2 of address
property1 of costLocation
property2 of costLocation
..

Best Falk
