Hello,
In Magento 2.3, I need to be able to make reservations by source id in addition to stock id. I am not able to do this through extending the ReservationInterface, as it is not extensible. Why isn't it? And how can I make reservations through source id without an extensible Reservation class? Would I create a separate module for a custom Reservation class and create preferences for my Reservation class?
Thanks
