Option to Wake Sleeping Workflow Tasks

Situation: A member of staff has put some of their tasks to sleep, and has now gone away on leave and their tasks have been delegated to somebody else. Some of the tasks that have been put to sleep need to be updated, but there currently does not seem to be a simple way to wake them to get them active again. We can redirect the items to the delegated staff member but they do not appear in their Workspace.

Suggestion: An option to change the status of tasks in K2 Management from Sleep to Active etc manually, without having to wait for the Sleep timer to finish.
