We noticed that when classes are cancelled, the blocked dates do not appear when generating invoices or the validity date is not automatically extended. Because of this, we have to manually extend the validity dates for packages affected by class cancellations or school closures.

It would be helpful if blocked dates in the calendar could also be shown during invoice generation, for example highlighted in red. This would make it easier to see that a specific date was cancelled or blocked, and that the affected packages need a validity extension.
