I'm not saying it's impossible, but it's probably a lot more trouble than it's worth to implement a solution that would do this. You would need to update the QVPR XML files as well as all Workorder XML files, while cross-referencing IDs, etc. If you take a look at those XML files, you can see how it works. For example, DistributionDetail.xml will contain records that reference QVSResource, which is in turn defined in QlikViewServerResource.xml. All these files are standalone, but all reference each other. The Workorder files are a different beast, and kind of combine the QVPR files into a coherent to-do list.
