With the latest update (3 October 2017) you can now create several projects with the same settings easily.
Just follow the usual steps to create your project.
When you set the name for the project - you can now select the option to create multiple copies of that project.
Each copy is assigned a name automatically which you can change.
You can not assign domains during project creation when using bulk project mode. You will need to assign them once the project has been created.
