I want to define the structure and the budget of the ship-model and only copy this structure and budget with every new project with same type.
I run several projects and during the execution a certain project I must change the structure and the budget (maybe it is related with some technical issue) of the following project and all project in execution (all projects are with same type for example cargo-boat).
I want this changes to be maded on ship-model level and then scatter automaticly to "copy" projects.
Is there any way to realize that?

As far as I know there is no possibility to update projects after you have copied from like a template project. No relationship between ' source' and 'target' project is stored.
If it would have been possible I would even be reluctant to update all target projects. I could imagine the status or phase of the project would need to be considered.
