Hi Sedelstein,
I’m not sure if you have a question about our product or base WordPress question. If I understand you correctly you want to set the capabilities for users / roles to specific pages.
This is not something that our plugin is for 🙂
You can read about roles and capabilities to have a better understanding how WordPress manages access to specific pages or actions (http://codex.ww.wp.xz.cn/Roles_and_Capabilities)
There are a lot of plugin that gives you the possibility to add new roles and edit the capabilities for example: https://ww.wp.xz.cn/plugins/user-role-editor/
In our pro version of Admin Columns, we have the ability to create multiple columns sets for your pages or posts and even assign them to specific users / roles, but I’m not sure that this is what you mean / want. You can read more about this here:

Since there is no reply on this topic, I’ll close this ticket.
