I wouldn't go so far as to say impossible really. I can't really give the exact details but it's essentially that we looked at doing it but there was a really bad performance problem that we don't have a solution to. It might be possible to fix but it is still a relatively low priority thing. Low priority, high difficulty, unknown time investment items get extremely deprioritized. I just don't want to get people's hopes up by saying maybe because there are just so many things we will work on first.
Now, also remembering that I'm really not trying to get your hopes up but this was the same answer we were giving to an old performance problem which forced us to cap the display number of active ailments on a target at 15 per type. This was very recently solved out of the blue and we got lucky and were able to take it from the "No" list to the "Done" list.
So barring some sort of epiphany coming to someone in a dream, for now it's just, No.
