While Jetpack doesn’t include any options to create Publicize templates at the moment, we’re considering such an option. You can follow our progress here:
http://plugins.trac.wordpress.org/ticket/1785
In the meantime, you could create a small plugin to create your own custom template, based on the code I gave in this thread:

Here is a temporary solution for this issue, i hope that Automattic guys add this functionality to the plugin, but meanwhile we are working on a better solution. http://outbc.co/1oSyIdu
@julius Doom I would strongly recommend against your solution, as it requires editing core WordPress files. If you’d like to bulk-customize Publicize messages, I would suggest using the code I mentioned in my message above.
