VIP App - Agent Notifications for Important Customers

We are currently using this simple app to highlight to agents our Platinum Support customers:-

However, it only supports a single option and we'd like to highlight different customers in different ways.

Is anyone aware of a way that this could be achieved?  We've had internal comments automatically added to posts, however, they drop off the page after a few comments.  We are looking for something to stay permanently at the top of the ticket.
