Welcome to the community
It completely depends on the requirement
- Say the relative number of items are less and some pre processing is needed then adding separately would make more sense
- On the other hand say the number of items are huge and all are available in a file for you to add then going will bulk add queue items will be better as you can add all at once and also you can add a reference column and provide references as well…here you have option to add all or reject if only few items do not meet the required criteria for the queue
