The issue is that the Watson IDE for R give no option for deleting individual Global items.
It is an all or none logic, which in my opinion is worthless.
It is a deal breaker for using Watson for R - also it seems the usage cost will only allow-me a week before running over.
The option you offer is interesting and useful and should be kept in place somewhere but individual deletion is important.
