Yeah, you can do that too in the old Dragon Age games too. You can set the IA with priorities to use one ability or another when something happens.
I do not know if this is going to be the final version, but right now you have to be a clairvoyant of sorts so you can set your reaction beforehand instead on using your reaction when needed.
Following the previous example you have to know that you will need to use absorb elements (or feather fall, or shield) instead of your attack of opportunity before you enter the cave because if you enter and the goblin shaman or goblin archer with a fire arrow goes first, you are going to take all the fire damage even if you have absorb elements prepared in your spell slot. (or shield, or free fall, etc)
