Entry into Indonesia twice in one month - multiple eVOA or multiple entry visa?

As per the title, I'm planning on going to Indonesia twice in a single month (going to another country and then back into Indonesia) - am I able to get two eVOA? How would this work - just get the eVOA, and then after I've left Indonesia the first time I apply for another eVOA? Or would I have to get the D1 1 year multiple entry visa?
