New Blog Templates - After Creation Automation

Hi Guys,

I'm using New Blog Templates plugin to create new template sites on my multi-site. What I want to be able to do, is after the new blog is created, create a listing on the main site based on the information of the new blog (title, etc).

So the post on the main site has custom fields and needs to populate the new site id (blog id) into a shortcode to link through some content.

Is there a callback / script / plugin I can use to automate this so when a new blog gets created that content is automatically created?
