Ignored user times

Is there any way to to find out how many days are left for ignored users? While I occasionally run into a bad apple I want to shut out for good, more commonly there’s some emotionally contentious event going on at the moment, say, an election or a high profile trial, and there’s one or two voices I want to leave out of the conversation just for that one particular event. Or there’s someone who I’m thinking of cutting out but might deserve a second chance. Temporary ignores are good for that, but because everyone gets put in the same list, there’s no way to tell them apart. (If I’d known that beforehand, I would’ve made a separate list myself.)
