retrograde option

[maxafax]

So I started playing just before the sa-lee event but that event was bugged which meant that they reset my progress to tutorial as a result I am missing sa-lee from my girl list and can not reobtain her until next December. It seems to me to be a bit harsh to have to wait a full year to get girls from events that have passed especially for new players just starting out. So It would be nice if once a month you could choose to do one of the past events under the same style (as if it was a live event, with same rules etc). This would allow players who missed an event or did not quite make it to the final stage in time to be able to have a chance of acquiring missing girls without having to wait for the event to come around again. Alternatively and probably preferred by the game manufacturers a event roll button working same as the gacha girl option but with previous event and gacha girls in the list rather than the new ones.
