Issue information in JSON format is available through the following REST call:
https://jira.[DOMAIN].com/rest/api/2/issue/[TICKET REFERENCE]
If the Issue is a Story with subtasks, the timetracking information returned by this REST call is either the following:

- or -

- or -

But, if you goto the website version and check the "Include sub-tasks" checkbox, the timetracker then updates on the website's graphical side to include all the sub-tasks time together.

Is there a way to include this checkbox value in the REST call? Can I make a REST call to an Issue that includes the sub-tasks in the timertracking section? Are there parameters I can include in the GET request for the REST call to have this option enabled?
Thanks,
