+1 for this feature
We are planning to build a quite extensive test repository which is completely based on WADL to create the services. We release 2 versions every year (and 2 additional minor releases) of our app in which a lot of WADL files are bound to change. We need a easy and fast way to update the content of these WADL files into our Soap UI (pro) project, preferably in a 'bulk' manner. Having this feature seems rather critical to the success of this test harness that we are trying to build.
I would be more than willing to go deeper into the requirements & use cases we will be performing.
