TimeTracking in JIRA REST/AGILE API

Greetings,

This is in relation to rest/agile/1.0/issue/{issuekeyorId}

If I create an issue then assign several subtasks/development tickets/defects/etc then I add ‘time estimated’ to the ticket, the parent ticket will show the total timetracking information on the website view (via jira.{mycompany}.com/{issuekeyorId}) but not store it in the API. Considering in AGILE most of the work’s time is associated in the subtickets it would be beneficial to add this to the parent ticket’s API rather than the time consuming looping GET over each sub-ticket (assuming you are doing an entire sprint at once)

Thank you
