I make characters for each monster I'm running, so I can have their attacks and everything predone before the game starts. I also prefer rolling randomly for each monster's hit points rather than using the average. There is a site called donjon that has an initiative tracker that allows dice rolls to be put in instead of set numbers. I'd love for there to be a way to do this in Roll20 when spawning a new token of a character. The hope is maybe check a box to say that a character is non-unique. An Orc for example, I could check this, set the HP attribute to 2d8+2 and each time I make a new token of the Orc, it rolls the 2d8+2 for the HP and assignes it to that token.
