Assign user to workflow status at task level

We would like to assign users based on workflow status at the task level instead of at the workflow template. Currently Wrike only allows us to assign users to status at the Workflow template level. This works great for teams where it's clear who is in charge of a specific part of a task, but for large teams where different users will be assigned to different tasks, this does not work. For example, the review status might be assigned to 'User A' in one task, but in another we would want it to go to 'User B'.
