Filter or Action hook on site-info.php?

Just making sure I didn’t miss anything, I checked the code, but I did not find any action hooks or filter hooks on wp-admin/network/site-info.php? Is there any page that calls site-info that has hooks?

I offer some custom features and it would be nice to be able to add a summary of how that site is using the features on the site-info.php page. I tried using a custom column for this on sites.php, but adding a column makes all the columns narrow and cramped and the page ended up scrolling, and scrolling and scrolling … until it became almost useless.

Thanks!
