Rescheduling of substitutions

In response to many requests, we have implemented a feature in Untis 2018 which has been asked for many a time: Now it is possible to reschedule a current substitution. If, for instance, a colleague is absent on Monday but will be back on Tuesday you simply drag and drop the substitution period from Monday to Tuesday. The colleague who was absent is now scheduled and the original period is cancelled. If the colleague was also absent on Tuesday an uncovered substitution would be the consequence.
