Configuring trash-box (Recycle bin) in Dell NX3100 NAS

We have purchased one NX3100 recently. I was just wondering that is there anything like the trashbox kinda thing is there in NX3100 once the user deleted the files. My old NAS box (Buffalo) had some options like that. If there is something similar is there  in NX3100, Please do let me know how to enable it.

Thanks & Regards,

Mathew
