[e-Newsletter] Creating newsletters for member groups

This might be extensive but my preferred approach to creating a newsletter would be to start with a Member Group selection, then create a newsletter based on a group-specific template.

The way it seems to work now is that we select the last newsletter that was sent to a group, clone/edit it, and re-send to that group. But we need to be careful not to send that to other groups.

Am I not using this correctly? This is a request to clarify how that works and possibly to modify it to flow more naturally.
