How to configure a axis with two outputs?

One axis corresponds to an SSI sensor and a proportional valve with a small diameter and a large diameter.
At low speed, use a small-diameter proportional valve, and at high-speed use a large-diameter proportional valve or use two proportional valves at the same time.
Like this kind of application, how should the hardware be configured.

The method I currently use is to configure two axes, but this method has a disadvantage that the number of axes is large, and more expensive authorization is required.

I just created a post that describes one way of doing this. On the RMC200, it requires only one feature key control loop. See https://forum.deltamotion.com/t/two-valves-on-one-axis-for-high-speed-and-low-speed/971
