TestFlight user management

Is there any way to do any kind of sophisticated user management in TestFlight?


We've got nearly 10k testers invited, and we would like to be able to find all the users who haven't accepted an invite in more than a month, or who have accepted but haven't installed a beta in more than a month, and remove them. Yet I cannot find any way to do this via iTunes Connect.


Surely we don't have to actually scroll through the list deleting users one by one... ???
