Would it be possible to allow a user to create a number of charging and exporting schedules that would only be activated by a month range.
So one might create a charge and export schedule for each season.
I guess the system would need to check that all months of the year were covered and there were no overlaps. And perhaps the system would limit the user to say 4 - 6 schedules of each type?
I cant think of a specific use case that might justify the need - but I think it might be the case that you could then set different limits/criteria for each schedule that you create which would be tailored to the time of the year that the month range covers.
