Prepare For Battle Interface

It would be lovely to be able to make quick last minute changes to your troops in the prep for battle interface - such as finding out I have some extra AP for my army, and can attach an extra unit to my army...but that unit has no hero...time to equip one!

But to do that, I need to exit the prep area and go back to my city. Integrating the interface would make quick changes, and downtime from battle even faster. This should include hero/gear equip/change abilities essentially.

Thanks for your consideration
