I usually have my tables set up in Excel, and copy and paste into a drawing. For Room Schedules, I export/copy the Room Name Symbol attributes, paste into excel. Sometimes I sort by room name, to group similar rooms and add the finishes to each group. Then sort on number, paste into the pre set table, copy and paste back into drawings. Or if I am good when inserting the Room Number symbol, I enter the finishes with invisible attributes that then can be exported/copies into dcad. Just need to rework the order of the attributes so they line up in the correct column order for my schedule.
Doors are done similar fashion.
