Folder synchronization is not something that Resolume is currently designed to do, and probably won't be in the foreseeable future. The flexibility Avenue/Arena give you in the form of parameter animation and layer control comes at the expense of things like file sync.
Other software such as VDMX and Modul8 are more geared towards "media bins" and the type of workflow you're describing. That said, a user here named cosmowe is pretty good with stuff like this if you really need a custom solution with Resolume.
