Is it possible to assign a whole group to a record during Excel/API import?

Hello,

We are currently using Unifier 20.12.

During the creation of a record via API, we are able to assign a specific user. But when we import a record in a post creation step of the workflow, it is not possible to assign a user to the record. It takes automatically the first user of the preassigned group list.

We therefore do not know how to carry out our data migration since we must assign each record to a specific user.

Preassign a single user is not acceptable and would not satisfy our client (Regarding the number of records we are importing, a single user won't be able to dispatch all records after data migration)
