No not really from Dreamweaver. It is not a Website entry, it is stored in a MySQL database table.
You would have to access it via SQL commands from the Administrator Control Panel or a 3rd party tool that allows access to the MySQL database, or a SHELL account on the system.
Sorry I don't know the commands right off hand to clear that for you or I'd help you. I don't currently have a local copy installed for testing. Perhaps Rick or one of the other guys here can assist you with that. (it's possible there is a method from within control panel but if there is I don't recall ever seeing it).
Hang in there and I'm sure one of the other guys can assist you with the correct commands to clear the view count.
