It is not possible to save one or more shopping carts
One use case is comparing different combinations of Offerings . In large companies typically not every user
orders new services / products . This is done by a manager or assistance . To get an idea of different
combinations of complex Offerings it would be good , if a user can save an arbitrary number of shopping
carts . The maximum number of saved shopping carts should be configurable in the application settings . It
should also be possible to configure a time intervall how long a shopping cart can be saved . After reaching
this time, the shopping cart can be deleted automatically.
