As BA/Super User, I'm not using every column (dates) in schedule for every client. Currently to save a schedule all fields in a period must be filled out so they are filled out with dummy data (for example 2020-01-01 00:00). It would be helpful for the system to allow adding "N/A" (not applicable) to the columns we are not using to replace dummy data. This will prevent confusion, mistakes and will give possibility for better maintenance by the local office and will make system more efficient. BAs will have the option to use the same structure for all the clients despite different frequencies and schedules that have to be created.
