New Post: Request: Custom Update Templates / Custom XML import

Hi David!
I'm exited about WPP 2.0, and maybe you've already added the feature but here it goes:

I think that we're missing the feature to 're-use' our custom made XML files.
Yesterday, I made a custom Java7u51 update, and I only needed to change the path to the Powershell script. I actually tried to export the update, and edit the XML slightly, but I couldn't figure out how to re-package the .cab file with the new .XML file.

Is there any way to make small changes in custom updates now?
If not, is it possible that you could add a way to do this in WPP 2.0?
It could be a .XML import feature or it could be a Custom update template.

Thanks,
Nikolaj Pedersen.
