I have to check one or two little things... but I think this should be possible. As said, Poser Python do not have the function to do it... directly.

But there is a workaround... I have to test it on props and will make a little user interface...

BUT... there is no way to know if a parameter has the 'Set limits' enabled or disabled. So it won't be able to display the parameters with the limits set to on for example.
