Is there an alternative to receiving activity data that isn't aggregated from Google Fit's REST API? - google-api

Question

I am trying to get specific data that relates to individual activities.
I can retrieve all data relating to all activities that were performed within a time frame (day).
However it is not specific as to which dataset belongs to which activity i.e. there is no identifier.
It does not come back in order either.
I tried grouping by 'StartTimeNanos' but that is not a solid solution as the data is in random order too.
Is there an alternative way to get back activity specific data?
I completed the following activities:
Google fit walk activity
Google fit run activity
and after making the following http GET request to : https://fitness.googleapis.com/fitness/v1/users/me/dataSources.
It returns all datatSources for user {me} : as 'source'.
I then use all sources mapped to the objects:
{ "dataTypeName": "source.dataTypeName", "dataSourceId": "source.dataSourceId" }
I then pass it in the body of the call to: https://www.googleapis.com/fitness/v1/users/me/dataset:aggregate
and the response is the following (with deleted values for readability here) :

As you can see, there is no way of identifying which point maps to which activity.
