Planning guides for IMRT hippocampal sparing IMRT

Does anyone have some good dosimetry guidelines for hippocampal sparing IMRT WBRT? We are trying to adopt this in our practice given the recent Ph III data and my dosimetrists are having to use 9 Arc plans to meet constraints. As much as I want to adopt this, 9 arcs for whole brains is not feasible for my throughput. Would appreciate input from those who have been able to get this accomplished with less arcs. Thank you
