Bulk Task Reassignment in Task Management Smart Service

Hello,

We have a business requirement where a number of users are assigned to a number of tasks. When one or more of these users are changed (added/removed) we need to update all the existing tasks that were assigned to this original set of users with the new set of users (e.g. original users were {Mr X, Mrs Y and Mr Z} and new users to be assigned are {Mr X, Mrs Y and Mr W}.

We want to use the Task Management Smart Service plug-in, specifically the Reassign Task feature but the 'Task ID' input variable only accepts single IDs. Can anyone advise how to bulk update multiple tasks using this smart service?

Thanks!
