Add object to Block Lisp Adjustment

All,

I've been using Lee Mac's "Add object to block" lisp for sometime now and it works great, and one of the things I use it for is my title block for revisions but now the revision block has been inserted into the title block as a block and it won't add what I want to the revision block. Is there a way to make it find the revision block inside of the title block? Basically I would to able to pick the block inside of a block.
