Embedding inside WordPress WITHOUT auto-insert

Hello. We need two things from analytics:

1. To not have any plugin auto-insert any code into our theme. We do not any wp_footer() functions for this purpose, not any wp_header(). We control our own header and footer template. I understand that to have this tracking, we need to manually insert the script tags from Gauge, yes?

2. If so, how should we enable a simple Analytics icon for *each* post via Admin Columns type plugin? Google Analytics has tools like GADWP (GA Dashboard for WP) which allow us to also put this tracker into the admin area, so each post or page has its own icon for analytics. This makes it easier for us to track our analytics by page and post right within WP. We don’t need to visit any other dashboards on analytics sites.

Could you please advise what we need.

Thanks!
