There're a few wishes floating about regarding the naming of viewports, and, after discussing it with various people, including Matt at VW, I wanted to make one that specifically requests auto-naming, and describes how it might work:
It would be a document setting called Use automatic viewport naming under Document Preferences > Display.
It would be indented under Use automatic drawing coordination and would require automatic drawing coordination to be turned on (this is because without auto drawing coordination turned on it's possible to have Viewports with the same Drawing Number and Drawing Title on the same Sheet).
It would be off by default when converting older files, to avoid overwriting Viewport names in older files when being brought forward. But it would be turned on by default in all of Vectorworks' template files etc. from that version onwards.
Turning it on in an existing file would warn you that existing Viewport names will be overwritten, providing an opportunity to cancel. And maybe a chance to undo the setting if accidentally activated.
The default naming format would be [sheet number] - [drawing number] - [drawing title]
But Viewports would have a setting that would allow you to modify the order (so, for example, you could put the drawing title before the drawing number in some instances). You'd be able to apply this setting to multiple Viewports at once (including when you have multiple Viewports selected on a Sheet or when selecting multiple Viewports in the Nav Palette or Organisation window). Each Viewport would remember this setting even if the auto-naming document preference was turned off and on again.
When mousing over the setting in Document Preferences the tooltip would read "Automatically names viewports with the sheet number, viewport drawing number and viewport drawing title. The order of these can be modified in the settings of each viewport."
Ideally there would also be a document setting to modify the divider, with the default being as above: " - "
