Get Project Progress for a specific group

Hey Guys,

at the Moment im calling

http://MYJIRA/rest/api/2/search?jql=project=P1337&fields=progress&category&maxResults=-1

to calculate the booked progress hours for my project.

What i want to do now is to order these hours via Groups.

For example i have the Group “IT” and the Group “notIT”

They are booking there hours to the Same Projekt “P1337”.

Is there an api call to only get the hours from the group “notIT” ?
