Ticket Search API - Is it possible to retrieve task info from a ticket api call?

I notice when I search for tickest using the API I see one of the properties returned is "Tasks", but it appears the array is null even if the ticket has sub-tasks.

Is there any way to retrieve any information about the sub-tasks or simply if sub-tasks exist when using the ticket search api?

Ideally if there was sub-tasks present we would see something like "Tasks": [taskid1, taskid2, taskid3] returned.

Right now I'm having to make separate API calls to check if a task exists which can be expensive if most of the results are null.

API call details:

Ticket search endpoint: https://api.teamdynamix.com/SBTDWebApi/api/{{app}}/tickets/search

Body: 

{
    "TicketID":  10957660
}

Returned:

{

....

"Tasks": [],

....

}
