DataDeploy question

System

Hi...I'm working on a workflow which sends a DCR to approval and once it's approved deploys to the user-defined database schema using Datadeploy. My problem is:
1. Is it possible to deploy only selected DCRs to the database.
2.Is there a way to check whether the attached file is a DCR or a static html(i suppose from DCR's EA)?
3.Can i use author_submit_dcr_0.ipl script for my case?
4. I've a oracle database table with 3 fields title, paragrapg and image.
Thanks....
