I remember I asked for this feature around 3 years ago and Aras said it´s a great idea! (TGVs were still a pretty new feature at this time). Never heard anything since then :-).
Which Innovator version do you use? Do you have tested the "Sorting" menu inside the Query Definition?
Translation: Right click -> Edit Query Element -> Sorting (or similar text).
As far as I remember the feature was grayed out in the past or didn´t sort reliable. I am not sure anymore. I have not tested if it works now.
So depending on your Innovator version, there is a change that sorting was implemented. It was definitely not a feature present in previous versions (11SP15,...). Would be happy to know your results!
Sorting enables you to sort data in the Ascending or Descending order. To sort a column, click the column header. To sort multiple columns, press and hold the CTRL key and click the column header. You can clear sorting of any one of the multi-sorted columns by pressing and holding the SHIFT key and clicking the specific column header.
