Can CDMS be used to modify the general building stock data in the HAZUS inventory at the dissemination block level

I'm hoping to modify the building count (by type) and their exposed value data in the HAZUS inventory using CDMS by importing a new shapefile with the data aggregated at the dissemination block level. However, I see that CDMS offers the options of either importing the file aggregated at the census tract level or at the dissemination area level, but no dissemination block level. So I was wondering if we simply need to match the fields for the DBuid with the DAuid in the importing process? Or is there another way to do this?
