Thank you for your forum post.
What you seeking is not currently possible in Source Control for Oracle and the work around is to checkout the required version from Source Control to a folder and using Schema Compare, compare the folder to the live schema and deploy changes.
I recommend that you comment and vote for this User Voice TOPIC.
