Manhole schedules need to feature cover types (D400, C250 etc), manhole types (Type A, B, C in Scotland etc) and whether they're a backdrop or a headwall etc. Having a feature to assign this based on location on site (cover type), depth to soffit (MH type) or based on their diameter I.e. <1.2m is an inspection chamber, <.15m is a rodding eye etc). This would be beneficial and reduce the extent of CAD tidy up required after exporting.
