Edit moduleshared across projects

Hello,

I'm new to IntelliJidea and I'm trying to plan a migration from Netbeans.

In Netbeans, there's no concept related to Module and Projects, everything is open in a single window.

In Netbeans I have 20 projects (not always open) and 2 of them are shared projects.

So, thinking in IntelliJ way, I'd group them into 4 projects and 2 shared projects.

So, in IntelliJ, I'll start to create the 2 shared projects.

Then I create 4 projects and I link the previously created projects as a module.

This way, The IDE resolves every link and they're working correctly.

But, being that shared modules are shared across 4 IntelliJidea projects, if I must modify a method or a class (for example I rename a method), how could I automatically get it refactored over ALL of the projects where I have that shared module?

I also tried the workaround to create only one project and create all my projects as module but I don't like it.

Thank you very much for your help.
