Another powerful feature of Automatic Field Calculations is the calculation series.
A calculation can only have one target field, hence you can only modify one field with one calculation. But what if you want to modify more than one field at a time?
In that case, you need to create multiple calculations, one for each field you want to write to. Then you want to group them in a calculation series because a calculations series can be run the same way as a calculation: manually from the add-on interface, automatically by assigning the series to a field or manually by clicking a button in the layout.
In the following video, we group two calculations into a series then we run the series: the two calculations take place and the two target fields are modified.
