Universities of course have maneuverability in the specific spine point they pay people for different positions based on experience or demand, but in the grand sceheme of things specific roles are paid specific amounts of money.
At the author's current university, for example, the national pay scale is split up into different pay grades (each of which includes a contiguous range of spine points) for different roles, e.g. Research Assistant, Research Associate, Lecturer, Senior Lecturer, etc.

In lot of places (and companies too) there is increasingly policies to avoid that.
