Question pre buy PRO version

Hi, I have to buy the PRO version of your plugin but first I want to understand if it solves my need.

I needed to accomplish the following:

1) The Administrator role must be able to create/modify/manage ALL wordpress users (OK)

2) I want to create a Sub-Admin1 role which must be able to create/modify/manage ONLY its own users. 2.1) Create a Sub-Admin-2 role which must be able to create/modify/manage ONLY its own users.

2.x) And so on. (*) The ability to create new users is not essential for Sub-AdminX.

3) It is also useful to be able to assign users more than 1 role.

Is this possible to do with your plugin?

Thank you
