Hi Dave, The problem is that we have different levels of metadata and documents. The documents are arranged such that we have a case for which there are multiple documents (files). When we use the mlt function, we do it on file-level, but it needs to be displayed at case level, which means that we need to group files that are connected to the same case.
Hope this makes sense.
