Aggregation question with custom TQL queries

I'm having an issue while editing an insiqht.

I think I've successfully figured out how to do a sum aggregation that looks for a particular value that I'm sending in a 'selector', and sums those values, giving me the total for the day (the custom query build is nice!)

I would also like to break this data down by user, so I can do the same summing operation, but apply a 'group by' (according to SQL) that will further break this down into which users are submitting the highest sums. Is this possible?
