Point to "Windows" -> Task templates. This way you create templates for tasks, and then you can pack those templates to a task package, which you can drag&drop onto different projects. This way you don't need to create the same tasks over and over again.

First, create a new task package:

Assign a good name for the package:

This task package will only become visible, if you add a task to the package. Create a new task template now.

Enter a subject for the task and assign it to a task package.

Your package now appears in your template list.

The next step is to group your list by "Task package":

After you've created several task templates and added them to the appropriate task package, you can drag&drop a package onto a project. Just click with the mouse and pull it into your project manager.

This way all tasks of the task package are added to the project.
