Is your feature request related to a problem? Please describe.
No

Describe the solution you'd like
I would like to have a way to start a clean project without having to manually delete all the test entities such as TodoList, ideally you can chose between 'clean' project startup and test entities with a flag. It saves a lot of time

Describe alternatives you've considered
None
