How do you change the axis of rotation of a robot joint?

How do I change the axis of rotation of a robot joint? If the joint is currently rotating about its X axis, how do I make it so it rotates about its Y axis?

You need to follow the directions in the video carefully if you want the movements to work correctly: Animation Creator, Part 4: Customizing the Robot

Particularly, times 1:30 - 2:16 explain that you need to make sure that the rotations of each joint are correct in the 3D modeling software before you import the shape into FlexSim.

If you mess with the rotations of the objects in the Animator in order to position them correctly, then the robot's movement code that determines how to rotate each joint isn't going to work correctly.

Here's a video showing a similar kind of robot when configured correctly: https://cloud.flexsim.com/index.php/s/CzDn8fGcHYqQsZj

I'm trying to model the universal robots UR10 in FlexSim as well, and what i am running into is that it appears the "standard" TE Robot joint 4 rotates around Y, but the Universal Robots Joint 4 rotates around X. Maybe it would be useful to be able to change the axis of rotation for each joint in the "geometry" tab.
