Different methods: Bottom-up and top-down in a single project?

Hi to all,

I am trying to manage in cProjects a single project that includes 2 methodologies (bottom-up and top-down) in the schedulling of a single project. For example 1 phase bottom-up and second phase top-down. In the creation of the project type it is possible to asign only a schedulling type.

Do you know how to solve this situation?

Regards,
