You can issue more than one command at a time, yes.
e.g., if you're using the "hold/speak" button, hold the button down then: say a command, pause for a second, say another command, pause for a second, etc. When you're done, release the button.
Or with the tilt: tilt up, say all your commands, then untilt.
I don't think I could say more than 2 commands in a row correctly, though.
If you pause too long, it probably won't work because VW is set to automatically detect a long silence (2 seconds) and will send the command when that is detected.
