HI usman ,
Thank you very much for your post.
To be honest with you ATUM does not have any similar feature as we are not working with orders management per user.
It is an interesting feature and I would like other users to post here if they think it would be good to develop it. There is a 'but' there though. Even if we get an interest in similar feature from other users, we are absolutely packed with work to do for another year.
If this is something you need urgently, I would recommend getting a developer to create this for your site only.
Sorry to disappoint with the answer.
