I don't mean to sideline the conversation, but wasn't the original posters comment more regarding the graphical side of rolling a 1d100, as opposed to the formulaic side? Last I checked, you can just /r 1d100 in the Roll20 chat, and that'll give you a 1d100 roll. I got the impression that OP was requesting an actual die, when 3D die is an enabled option, rolled on the table. As it stands, the /r 1d100 roll is just in chat. This is a personal point, but I've often found rolling 2d10 on the table more fun than the d100, but that's due to live games having the option to actually roll 2 trapezohedra with clear markings based on which is the units and which is the tens. As far as I know, rolling 2d10 via 3D die doesn't give the option to differentiate between the two die rolled, so deciding which is the tens and which is the units could be in dispute. Edit: Rolling 2d10 via 3D does still give the number in the chat, so the DM stating the first number being tens and the second being units in the sequence offers a method for ruling which is which.
