Persistent Atlantis Chest progress indicator

It would be nice if there was an indicator somewhere other than on the Atlantis Summoning gate to indicate where one stands relative to the filling of the Atlantis Summoning chest. This would be helpful when deciding how to use, or more to the point, to save gems for different types of summons. There is an indicator that can be checked at any time for every other type of chest one can fill and open, but not for this one. Maybe add it to the bottom of the Summon screen or to the player profile page?
