Studio's Morphloader Pro is NOT a solution for Poser. I bought it and worked with it extensively but the results were dissapointing. I only kept it because there was no alternative when it was released.

While any joint fixes made with MLPro work perfectly in Studio, they are seriously lacking when you load the figure into Poser.

Joint fix morphs need to be 100% precise, and because Studio and Poser calculate joint deformations slightly different, a Poser joint fix won't work in Studio and vice versa.

So:
If you want to fix joints for Studio, you need MLPro.
If you want to fix joints for Poser, get ColorCurvators script.

Poser and Studio handle joints already too differently for a single solution.
