In the Lost Grove, battles are made fairly easy of clicking the key of the move you want and pushing 1 to auto place the move on the 1st available target, This is very useful, except when you want a different target. I personally find constructs to be easier when shifting the target onto a second construct when they have their shield up, and I think it would be a great idea to have the 2 and 3 keys set to target the 2nd and 3rd available enemies. This would also help with many named battles as they have those companions that usually need to be taken out first.

I thought this already worked? I usually click, but I just tested it out and 2 worked for me.
