Has there been any words on if/when we'll get this feature?

For those who don't know about it, essentially it is a button for story missions that lets you instantly 3star complete it and gives you randomly generated units from the map, as if you had run the map yourself. It only works for story mode and requires you to have completed both 3star and drops for the mission.

I would love to have this feature as running Flame Dragon over and over is getting a bit tedious, so i'd rather just run my missions and be done with them. The daily missions and events do not appear all the time so i like running them, especially just for looking at that specific unit that drops the thing i want and go "YES IT DROPPED!"
It's just the story mode missions that are getting a bit tedious -_-
