HI There,
I've had a look at your issue. In most cases instances of family tables have a lot of similarities, hence the reason they would be created that way. There tend to be small differences that require only small changes to information such as notes.
You haven't given any examples to show a context to your question so it is difficult to know what you want to change between the instances.
So, I would say you cannot really take a whole note and change between FT members. Mostly I would add a parameter or dimension in the notation so each variant drives that part of the note. This can also be done for materials and mass properties.
If you give me more of a context then I might be able to help you.
