Blender to Trainz: Blender 3 Beginner Course - 20 Fruit Box Modelling

Hi, I've used Gmax for a very long time and looking to move onto blender. I've got 3.5 installed. Something I've noticed is increasing the number of vertices / polygons in an object seems a lot more work in blender than in gmax or am I misunderstanding the tutorials? In gmax with a cube you could quickly alter the number of subdivisions/faces by simply increasing the number defined for the object. It usually copied the spec from the previous object that was created or modified then just change the number of divisions. With blender it looks like you have to manually add each poly / vertice individually using subdivide. Is that true? Thanks, Gary.
