"Select All" vs. "Select All + New"

So here is a problem I constantly struggle with; How to communicate that the user can pick either all items in a given list vs. all items in the list and optionally all new items that may be added to that list.

Consider the following example; let's say we want to assign a user to one or more groups. Most of the time, an administrator will pick one or two groups from a list. However, for special users, users who have multi-hat positions, for instance, administrators want to pick all groups, including new groups that may be created in the future.

Just wanted to hear what you guys think about this.

Here is a not so great example I hope to improve on;
