I would like to know how in the "Cookbook: Single Post" i can add a post that I choose (with an ID by example).
I'm not sure I understand the issue well enough could you please elaborate little more. Also, do you mind sharing a screenshot of what you are trying to achieve? so i could understand and help you to fix the issue.

Unfortunately this isn't something that's currently possible. There is no option inside visual composer and it requires customization.
