Admins are limited to adding 1 subscriber list

Hi all, I have 1 super admin setup that has access to all lists in all categories. Individual admins do not have this option. Individual admins can only have 1 subscriber list. Is this something set in the config.php file?

Error: You cannot create a new list because you have reached maximum number of lists.

Also, what is the best way you can recommend that one can setup campaign content templates that all admins can use/share individually?
