international data roaming in Canada

I travel routinely to Canada and learned the hard way that I need to keep international data roaming off most of the time. Searching the forums I found how to use AnyCut to make a shortcut to toggle network settings but I couldn't find the following:

(1) Is there a way to create an anycut that goes right to CDMA roaming settings? My existing any cut will take me to the menu above that so it is only one more click.
(2) Is there a way to leave international data on but only for email?

(3) Is there an App like Shush (which is for ringer) that will turn on international data for a set number of minutes?

Thanks

 

Can anyone help with this?
