I've table that stores car information. I want to have model and mark data. The solution is to create Model and Mark tables:

Model -> has_one Mark
Mark -> has_many Model
Car (main table) -> has_one Mark

I've created additional Tab to define car Mark (in cms). On this tab is standard link "Add Mark". This links opens popup window where new Mark can be defined. How can I extend this popup to add Mark and Model at the same time (with adding correct relation beetwen Mark and Model)?

I can define direct relation beetwen Car and Model but this is redundant.

Thx for any help
