Initiate Wireless connection when start syncing
 

At home I sync my OmniFocus on the iPhone with my web dav server wirelessly.
Unfortunattelly when I open the app(after having it running for a while and teh phone going in standby lock modus), and there is sometimes no sync button available.
This is because the wireless is not active in the phone(it is switched on, but not initiated).
I have then to go to the browser or so, to initiate the WLAN getting active again and then I have teh sync button.

Request:
Sync button should be always active and when pressing it, the WLAN connection should start. (Like in safari)

Remark: Wirelsss is always on and I have always a wireless network availble
