I have a scenario where the out-of-the-box IIO Multiple rows per record feature isn't working (unsorted input data). As you know, this feature creates nested arrays of grouped records that IIO then treats as single records. I'm wondering if I can create my own grouping in a script? Can I take ungrouped input records, group them and hand the callback a nested array of grouped results? I'm not sure if it's simply the format of the JSON that provides all the hints to the system or if there is metadata behind the scenes that tells the system to treat the data as grouped.
