Factory Calendar - New Import Feature

Having the possibility to import a custom calendar in the factory calendar would be great for rotating shifts. As we have different shifts with changing working hours every day, it would be very helpful to have the possibility to import the shifts patterns (as a .csv for example), as it would allow us to build our calendar for the next 12 or 24 months and import it in the factory calendar. Otherwise, I have no other option at the moment than manually entering custom working hours every single day.

Thanks
