Can the PM of an external translation agency (external manager) assign documents within a job to different workers (external worker limited)? One cannot predict between how many people they will split the job, so it seems logical for them to be able to do this.
One job can can be always assigned to one worker only.
For Standard projects we can have multiple documents in one job while for CodyT one job=one document.
So for one who is going to assign each document in a project to a different supplier the solution would be to use CodyT projects instead of Standard project since this way PM avoids the necessity of creating many jobs to enable external agency to freely assign jobs per document.
