How can I create a saddle that can alter the Dino's BP values?

Another way I could do it is to modify the values in the status component:

I tried to make it so that the saddle doubles the weight capacity, but nothing happens. I tried with the function “Set Max Status Value” and it worked just fine, but the problem with that is that it adds the exact value I input.
