Automatically create a PDF file of the substitution plan

Transferring the data from Untis usually takes about 10 minutes. A pdf version of the substitution plan can therefore only be generated after this delay. For the daily work process, it is very inconvenient to always have to remember to save the plan in ten minutes. Therefore, it would be helpful if a pdf version of the substitution plan is automatically generated every ten minutes after the Untis import.
