App Center for different projects

I plan to create several projects in Lianja. Each project should have its own app center. At the moment I have all the apps including the example apps available. Now I have published some apps for Project A. Now I want to publish other apps than Project B, but they are not allowed to appear in A's App Center. How should I proceed?

If you create a project only those Apps included in the project will appear in the App Center.

If you want to combine several projects then add the Apps from project A and Project B into the new project.
