If a campus is submitting a multi-disciplinary comprehensive ENH, do we need to submit required information on previous BoRSF awards for each academic unit involved in the proposal or just the lead academic unit submitting the proposal?

It is ok to limit information on previous awards to the lead unit, especially in Comprehensive. The intention was to keep to the spirit of the newly organized Departmental version of Enhancement that emphasizes the department over the PI. But five years for an entire department is enough to sort through for the applicant, and enough for the reviewer to process. However if the applicant feels that listing all the departments’ BoRSF history helps make the case, then feel free to do so.
