I'd like to add a required asterisk to all cell types, but I'm not quite sure of the best way to do this. If I was just customizing a specific type of cell, I could subclass it and implement it there, but since I want it to apply to all cells, it's a little trickier. Basically I want it to look like this:

Since it's a different color, I need to use a separate label, unfortunately. Any thoughts on what the best way to accomplish this is?
Thanks!
