Upgrade em at one Go !!!!!!!!!

Tired of upgrading every single wall one at a time, boring!!, SuperCell has come up with a best of its upgrade, "Upgrade all at one go"

 

 This upgrade has two benefits that it is bringing, number 1 is probably that no more selecting every wall and upgrading them one at a time, just select the whole row and click on upgrade and , BAM!!! upgraded.

Also another great feature is that along with this upgrade will come the feature of upgrading the wall even using elixir.
wanna upgrade walls but don't have much gold while your elixir storage is overflowing with elixir? boom!!! you can have them upgrade with elixir as well after this upgrade.
