Control Constraint Priority Programmatically

In my plugin I need to change constraint priority, the only info I found about this is here:

https://knowledge.autodesk.com/support/motionbuilder/learn-explore/caas/CloudHelp/cloudhelp/2022/ENU/MotionBuilder/files/GUID-D7CAD565-FF0F-416B-B709-C8DAD7A42E52-htm.html

However it seems like there is no way to do this programmatically (either C++ or python).

I tried to do a test by moving the last constraint to the first position however this is not allowed

import pyfbsdk scene = pyfbsdk.FBSystem().Scene # Test, try to put the last constraint in the list in the first position constraints = scene.Constraints myConstraint = constraints.pop() constraints.insert(0, myConstraint) # Returns the following error: # Traceback (most recent call last): # File "<string>", line 1, in <module> # NotImplementedError: can only insert at the end of a property list

Is there any way to do this? Obviously you can do in the navigator, however I did not see any way of doing it in my plugin...

Any help would be appreciated.
