The documentation says this about project settings:

So maybe you can try and copy all the altered .ini files from one project into your new project. You find them in your project folder in the “Config” folder. Just don´t copy the DefaultGame.ini, this contains the unique game ID, and i guess, every project should keep it´s own uniquie ID ^.^
