That sounds great. I missed the last medal on the first 2 events after launch, due to having rather weak party at that time. Thus both my Lavender and Edelveis lack one Equipment slot.

If its done like how its described above then its not only saving a lot of my time, since I don't need to redo the whole event, but also doesn't waste all my stamina since it will be running parallel with a new event that will become the main focus as usuall.
