Mobu constraints: getting/setting the offset property

Is there a way to access the translation/rotation offset of a constraint via python?
Only the Snap() function is mentioned in the docs, which is only good to set an initial offset.

What I want is to key that offset across different takes in a multitake file, so that each take will ‘remember’ that constraint’s offset.

‘myCons.PropertyList.Find(‘Offset T’).Data’ yields no results.

Anyone has tried something like this?

Some replied at the area forums, the property name has to be just like it appears in the property window (i.e. must have the name of the source object in it)
myCons.PropertyList.Find(‘Left_Hand.Offset T’).Data
