Multi-stack selection info

You used to be able to select multiple stack and it would 1) give you the information (hp/attack stats etc) for a hypothetical combined stack and 2) give you the march time of the longest march based on where the cursor was when using "Move". For the first this was quite useful for thinking about combining stacks or just knowing the total attack and HP of multiple stacks. For the second it was very useful for determining the optimal position to march to when combining stacks. It would be nice if these features were reimplemented.
