Seconded.
But in waiting for this feature, I also start getting used to forge to overcome this problem. I don't mean aggressive and resource-exhaustive forge. Just do it daily. Whenever you pull 2* or 1* from Alliance, Free Daily or PB crystals, upgrade them to a reasonable and affordable level before feeding them to one of the 4* bot of the same class or preferably the same bot. You can do it with mods too. I use to have over 1K+ of ores in the stash, now there are 200+.
