The main idea is to add Bulk Delete in the API,
The API currently has Bulk Add / Update but not delete, and the bulk delete should follow the same format.
Hence it means a large amount of API calls to delete 1000 options on a drop down. One work around is to delete the field and start again but that involves rewiring the field logic that was in place and in some cases you only need to delete some of the fields, so it would be helpful to have and it would also mean less traffic on Workfront servers, so an improvement for WorkFront and the customer.
