Star Rating Notations

I would love to be able to make a notation in the Star Rating tool for what each rating means. I don't use stars for order of preference, but for sorting and filtering different types of shots. Often I go back to a session and forget what 1, 2, or 3 stars meant to me at the time. There seems to be room between the Stars and counter for a note to be written here about what the rating mean. 1 star "Daylight Exteriors", 2 Stars, "Dusk Exteriors", 3 Stars, "Interiors with Blue Paint", 4 Stars, "Rush for Client"
