Perhaps the issue would be clearer in JSON notation. We have

"Filter": "(f1 > 0)"

What I suggest is

"Filter": { "Text": "(f1 > 0)" }

I don't see where you're going to shoehorn in any additional information
without the container, and once you have the container you need to name
the property, no?
