Is it possible to generate more than one document in one operation?

Yes, of course it is possible, although the exact number of documents that can be generated in one operation depends on the type of subscription.
The document generator makes it possible to create several documents in one operation from one form – for example when some of the data is common to all the new documents – then you don’t have to enter them again…
All the documents that must be generated in a single operation are grouped together under a “collection of documents”, and the collection of documents is attached to the digital form.
