Add a new block on member's blog postings

Hi!

I would like to add a new block on my member's blog post and also place it on top of "description" box. Please let me know how to do this. I search in my admin and there's no way I can add it in the Builders>Page builder as there's no "blog" link there. It's only got the following link where I can add blocks.

• Classifieds
• Homepage
• Account
• Shared Music
• Shared Photo
• Profile
• Shared Video

Please refer to this screenshot on where I want it placed-->http://filipinobusinesslinks.net/screenshots/blog.jpg

All help will be appreciated!

Thanks,
Sam
