Misc Destination with a Pause


Is there any way I can setup a Misc Destination to dial a number (E.G. 0800123456), pause for for 2 seconds (to allow the auto attendent to kick in) then dial 123 (for the extension)? It’s so I can setup a misc destination for my work (I don’t have a DDI). I read that you can use w’s in the dial string to get Asterisk to pause, but the admin screens won’t let me put that in. I tried hardcoding it into the MySQL database and updating the configs, but that didn’t work either.

Any help would be most appreciated!
