Shifts can easily be imported into a new weekly plan using the import function. First of all you create a schedule and save it as a template.
You can include this template or parts of it in another schedule at any time using the import function.
First you create a new schedule by klicking the plus in the schedule navigation bar. In the second step click on "Actions/ three little dots" and then on "Import shifts".
Select the desired schedule template and decide whether you want to copy assignments too, and also select the departments you want to copy and finalize the process by klicking "save" only once! It will take some time for the copying process.
