Hello MrT,
That is an excellent question. Because of the complexities and fluidity of any given companies' network environment, Asset-related views do often times have some redundancy in what they report. For this purpose we include a number of views in c.Support for looking at your assets, two of which will aggreggate the scans by machine name. Perhaps try the views "Asset - Inventory Scans by Machine Name & Software Title" and "Asset - Inventory Scans by Machine Name & Hotfix."
Further customization of any view definition is possible, but would necessitate a discussion with GWI's Professional Services Team.
Hope that helps.
Eric, Adam, and John
