Attachment Datamanager: Possible to set the userid?

[jwocky]

I have a custom script which successfully uploads an attachment to a thread using vbulletin's datamanagers. However, I want the script to assign that attachment to a predefined userid and can't figure it out. Does anyone know if its possible to do this at the time of creating the attachment, or after the fact somehow even?

I haven't tried it, but after you've created the attacment object, try $obj->set('userid', id).
