This is a new feature in 8.1.1. And since my env is not a published release, may be you cannot achieve same thing in your env. However, may be you can approach this functional in 8.2 in future.
1. Go to Siebel Code Generator to generate EJB codes for BS:AccountAttachment. You can find this toolkit in Siebel Tools.
2. Deploy your EJB to application server
3. following is my codes of creating 1000 accounts.
