Saved Query partial update of nested array

[masojus]

Investigate what happens when trying to do an update of a Saved/Cached Query definition such that an element in a nested array is the target of the update. Filters, Funnel Steps and Group By parameters come to mind.

I suspect that right now this works if your target update is the entire array, and you set an entire new List<Map<String, Object> as Filters or Funnel Steps, or a List<String> as Group By params. Ideally one could pass a List<Filter> or List<FunnelStep> or something, but that seems like a lot of work. Right now I think when it sees the List<> as something that's not a Map<> it'll stop there and set it as the new property.

Additionally, you really probably just want to change a single property in a particular element in the list, so maybe only the filter op of the 2nd of 3 filters needs to change from gt to gte so how to express that? If this were a realistic scenario, one would send something like this as the conceptual partial update:

{
  "query": {
    "filters": [
      null,
      {
        "operator": "gte",
      }
      null,
    ]
  }
}

Really, this sort of nested complex update is probably A) not common, B) even less likely to happen in a scenario also involving remote collaborative changes to the same query, which is the source of part of the problem solved by partial updates--to not lose remote changes, and therefore C) better handled by just re-creating the query definition from scratch (which avoids dealing with disallowed properties being sent, like last_modified_date and friends).

Thoughts?
