possibility to run a specified phase on newly generated project

I am integrating some code generator into Maven.
> Currently, I have a project archetype and a plugin that wraps the generator.
> In the current arrangement creating a project is a three steps process:
> 1. mvn archetype:generate <parameters>
> 2. cd <project-dir>
> 3. mvn package/install/whatever
>
> I would like to make it a one step process - like:
> mvn archetype:generate <parameters> -DrunTo=package
