Feature Request: Track airport lounge visits

Since CardPointers is useful for quantifying the value you get for your annual fee, it would be great if we could use it to track our airport lounge visits. Since all lounges are not created equal, the ability to assign a value to a lounge visit would be a necessity (i.e. $X for Priority Pass, $Y for Centurion Lounge, $Z for airline's lounge, etc.). Ideally I'd like to see a default but customizable value for each type of lounge since, for example, not all Priority Pass lounges deliver the same value.
