Include sub-task time on "customer" project cases

[Milenko Milic]

Is it atlassian allow option to include project task's time on parent case (Customer project) like we have on project sub-task's (Internal project)?

If I add task under Customer project but task with type project sub-task i have that option to include but only case with this type .

I need this one to be on case type Project task.

Thanks to all for answers upfront

You would have to worklog  turned on and then write a JQL with function time spent for the standards issue linked to parent. Or put the project in Plans (advance roadmaps) : https://confluence.atlassian.com/jirasoftwareserver0915/roll-up-values-to-parent-issues-on-your-timeline-1402412030.html
