Perform ABC Assignment from the ESS is not happening for the last few items in the sequence

Summary:

Client has more than 100 orgs for which they need to run the 'Perform ABC Assignment' job. The 'Perform ABC Assignment' is scheduled but when newly created item is introduced to the ABC Classification Set it increases the sequence in Classification Set.

Hence, the last item will be excluded as we have one more sequence generated and class level cutoffs still remains same. Whenever class level cutoffs changed(i.e. new item created) customer needs to submit assignment group via Manage ABC Assignment Group ->Submit action of Perform ABC Assignment Group.

So to do that manually for each org from Setup and Maintenance is not feasible. Is there any other way this can be achieved?
