Inventory Folder Size for all file types

Per the discussion in this locked thread, https://www.symantec.com/connect/forums/file-detai... , I would like to Inventory two folders on D:\. I've set up an inventory policy which runs as expected, however the only file size counts reported are for the defined FileTypes. Is there a way to have it count the whole folder size (including subfolders) regardless of the filetype? I can do this with a custom inventory but I was hoping to use the built in policy. Thank you.
