There are situations where import task is stopped - either on the request of administrator ("suspend"), because of error, or simply because of system shutdown.

It would be fine to allow restarting such a task from where it was stopped, not from the beginning, as it is now.

(This would require the task to record its current state somehow; which could be a problem because the resources - by default - do not provide list of accounts or other objects in a sorted way. The requirement would be to have a resource that is able to sort objects and then to define a sorting criteria.)
