Is there a way to update the allocations (particularly for Non Project Investment Objects (NPIOs) such as Other Work) aside from manually changing the allocations for each team member on the Team tab in PPM? 
One option would be using XOG to update multiple team members at the same time. See KB000012621 for details on the XOG template that can be used.
