Default Starting Wifi Tether Router with Tasker

I'm using Wifi Tether Router to enable tethering on my EVO 4G LTE. Right now I have Tasker set to launch the app when I connect to my car's bluetooth, then I press the "Enable Wifi Router" button to start tethering. What I'd like to do is have tasker start the tethering action, I'm just not sure how I can get it to do this. Wifi Tether Router has a widget too, but I don't know how I could get tasker to press the widget button either. Does anyone know how I can get this working? Thanks!
